How to Sew A Backpack with Cordura or Kodra Material

how to sew cordura backpack

TuffSew here, your heavy duty sewing machine manufacturer! So you want to learn how to sew a backpack? Maybe you just want to learn more about Cordura materials? If yes, you found the right article.

The first backpacks of our time were made of “cotton canvas” material waterproofed with wax coating. The problem with this was the material combination was very heavy. Also, the waterproofing was inadequate. 

One of the reasons backpacks were made of cotton canvas was the fact that they were very inexpensive to produce. 

This low cost to build quickly translated poor quality and low durability.

Today, if you are looking to manufacture a quality backpack…you’ll want to use Cordura or Kodra fabric. These fabrics have a rough fuzzy texture and used in all high quality backpacks. Compared to normal canvas, the Cordura is very lightweight and abrasion resistant. 

Compared to cotton canvas, polyurethane coated Cordura or Kodra is waterproof. You could use a nylon weave, but they are much heavier and not sought after as much in the backpack industry.

When looking for a superior strong, resistant to tearing and durable backpack, you should definitely consider military tactical backpacks. they can be made of both: Cordura or Kodra fabric.

Other advantages with Cordura is resistance to tearing and scruffing. Intense backpackers travel next to trees, brush, and rocks. They appreciate the durability of the waterproof travel backpack Cordura fabric and will spend extra money on a quality made backpack that will last them several years.

In terms of lifetime usage, overtime the polyurethane coating will eventually wear down. This is due to sunlight, exposure to water/salt water, chemicals used in cleaning, and storing the backpack in a damp area. 

Advise your customers to completely dry off the backpack before storing it. There are several quality levels of Cordura, so do your homework and find one that may be guaranteed of the weardown of it’s coating.

Now that you’ve selected Cordura or Kodra to be your material for your backpacks…..what sewing machine should you use to stitch it up?

Here are 5 tips for sewing cordura: 

1) Look into a built-in walking foot sewing machine. 

Our TuffSew Straight Stitch and TuffSew ZigZag are heavy duty, semi-industrial type sewing machines. Using a sewing machine with a built in walking foot is best because the walking foot is motorized and pulls the fabric through the sewing process from the top of the fabric. In conjunction, the gripped style feed dogs in a walking foot sewing machine pull the fabric from the bottom of the material. This top/bottom pull action gives you ultimate feeding ability when you sew Cordura or heavier type materials.  With a built-in walking foot sewing machine, you can sew many layers up to 1/4″-5/16″ thickness.  Here is a picture of this portable walking foot sewing machine and a true built in walking foot (the top portion):

For best results, do not use a standard household sewing machine when sewing layers of Cordura for backpacks. These sewing machines use a walking foot attachment.  Below is an picture of a walking foot attachment. This is what you DON’T want to use if you are sewing Cordura or Kodra fabrics. You won’t be able to sew more than 1 or 2 layers.

2) Make sure and increase your stitch length to the maximum while you are sewing.

 Some walking foot machines have a 5mm stitch length, others might have a 5.5mm or 6mm stitch length.

3) Use the largest size needle available. 

With most walking foot sewing machines, you can use up to size 21 needle.

4) Ask for a “slow” type foot pedal (some call it a carbon-elemented foot pedal). 

This will be a big advantage when sewing layers of Cordura. Take your time for best results.

5) Use a heavier type thread. 

Another great reason for using a walking foot sewing machine. Standard sewing machines can’t handle nylon bonded size 69 thread…but a true walking foot sewing machine can.

Lastly, if you want to learn why an industrial portable walking foot machine has advantages over a standard sewing machine…see this video:

How to Sew Marine Canvas

how to sew marine canvas

TuffSew here, your heavy duty sewing machine supplier. Here at TuffSew we get many questions about “How do I sew Marine Canvas?” First of all, what is marine canvas?

It’s really a phrase that encompasses dozens of materials such as acrylics, polyesters, and many coated meshes used in the outdoors. 

These materials are usually resistant to water and also resistant to harmful UV rays. You’ll see marine canvas applications used in awnings, tarps, boating materials, tenting materials and many more. Now let’s go over some tips and important things to remember when sewing marine canvas.

The Tools You’ll Need to Have

A Walking Foot Sewing Machine

First off is a heavy duty walking foot sewing machine. We recommend our Tuffsew Straight Stitch or TuffSew ZigZag sewing machine.

One of the sticking points to sewing marine canvas materials is your stitch length. 

Make sure you use a long stitch length, somewhere in the neighborhood of 5-6mm. We’ve redesigned our walking foot sewing machines to have a longer stitch length than any other walking foot sewing machine in the market today. This helps our customers sew through the heaviest fabrics.

The Right Thread and Needles

For needles, you are going to need size 18, 20, and 22 needle, type 135×17.

You’ll also need polyester thread sizes ranging from #69, #92, or #138.

Thread color? Well that depends on your level of sewing ability. If you choose a thread color that highly contrasts your material, and you are a sewing beginner, then expect to see your errors. We’ve seen some beautiful projects with highly contrasted thread/material, but make sure you can handle the added pressure of nailing those seams.

The Right Foot Pedal

Make sure you are using a foot-pedal that has speeds that are slow. You want to make sure you are in control of your project at all times. You also want to check your tension. If your material is puckering, than you have set the tension dial too high. 

If you are seeing loops in the seam, then you aren’t using enough tension. Make sure and use a test piece of material before you sew your actual project.

As long as you are using the correct type of sewing machine, needle, and thread to handle your thick marine canvas materials you can sew like you would on a normal household sewing machine. The key is, use a walking foot sewing machine….and with our longer stitch length we feel like the TuffSew Straight Stitch or ZigZag sewing machines are your best choices.

How to Sew Leather with a Heavy Duty Industrial Sewing Machine

how to sew leather

TuffSew here, your heavy duty sewing machine supplier. So, you have decided to start sewing leather. Here at TuffSew, we get one or two questions a day regarding sewing leather. 

The most important question to ask yourself is “what sewing machine am I going to use?” Let’s say you have a regular household sewing machine that you plan on using for this leather project. Will it sew your new leather project? The answer is maybe. There are many variables you need to be aware of.

First, your household sewing machine takes a maximum needle size of 19. Will this handle some leather? Yes, it will. But that size needle is pretty thin….and will only work on SOFT leather products with thicknesses from 1/16″ to 1/8″.

One of the biggest problems people have when using a household sewing machine for leather is they think they can sew 1/4″ thick or greater. If you do this, chances are you will break needles, skip stitches, and stall out. If you truly want to learn how to sew thick leather up to 1/4″ thick, make sure to research machines such as our Straight Stitch Industrial Portable Sewing Machine for leather.
 
TuffSew Straight Stitch Walking Foot Sewing Machine
 
The Straight Stitch can take up a size 23 needle! This size needle looks and feels like a nail…and will penetrate your leather projects very efficiently. This machine is manufactured with a built in walking foot. 

This walking foot will grab your leather material from the top and the bottom…evenly feeding your thick material through the sewing process. Here is an image of the walking foot:
Built In Walking Foot
 

And here are the 7 additional tips when sewing leather:

1) Don’t buy the most expensive leather the first or second time you sew leather. 

A lot of times you can find scrap leather from a local dealer at very high discounts. Remember, practice makes perfect. Learn how different thicknesses of leather need different needle types, sewing speeds, and varied lengths of stitches.

 

2) Find a knowledgable leather supplier, someone you can trust. 

Give them detailed instructions on what your application or project is, and ask them what they recommend you use.

3) Use a rotary cutter to cut your leather skins. 

You should also be using some weights to keep your material in place while you cut.

 

4) Sewing Leather takes time, slow down. 

If you don’t have enough time for your project, then don’t start it. Manage your time and start back up when you can give 100% of your attention and effort to your leather sewing project.

5) You can press leather with an iron (other side of hide).

6) Don’t use pins on leather as they leave holes. 

Ask your leather provider about clips.

7) If you are sewing 1/8″ thick or greater, make sure and use a presser foot that is grooved. 

The TuffSew Straight Stitch Machine has this grooved presser foot. The feed dogs are also grooved. This will give you the benefit of true grip when you are sewing. You want to be in complete control when sewing thick leather- so make sure and get the right machine for the job.

What Tools Do I Need to Sew Canvas for Boating Projects

how to sew canvas

Before you start diving into do-it-yourself canvas sewing work on your boat- you need to make sure you have all the right tools for the job. You are going to need a heavy duty sewing machine, some thick needles, some thread, a good pair of scissors, and material. 

You don’t need to be alarmed and go buy a $1,200 dollar sewing machine. A simple walking foot sewing machine with a built in motor will do.

We recommend our TuffSew Straight Stitch 9” heavy duty walking foot sewing machine for all of your sewing projects. There are two different size TuffSew Straight Stitch machines. One has a 7” gate the other has a 9” gate. The gate is essentially the amount of horizontal working space from the left edge of the sewing machine to middle base of the machine.

Let’s get to material. You have primarily 2 choices at this point. You can go with the standard in the industry “Sunbrella” which is acrylic – or natural canvas. We do recommend using Sunbrella however the price is 2-3 times higher than natural canvas.

Next on to the recommended thread! If you are new to sewing it’s important to use the same color thread as your material. You certainly don’t want to show off your errors. Light colored thread on top of dark material does look fancy- if you are up for the challenge. 

The type of thread you want to use is polyester based 69 or 92 weight. A simple google search will place in on websites where you can order all different colored threads for your particular project.

Needles and the correct sewing machine are next and the most important topic on this article. The following hypothetical situation happens daily… So you are excited….let’s say you bought your Sunbrella material, bought a great pair of new scissors, and bought your brand new 69 colored thread. 

You wake up early one Saturday and take out your regular household sewing machine and needles. You start to sew…but the needle not only won’t penetrate ¼” thickness of material, and the needle starts bending and then they keeps breaking. DON’T PANIC! It’s not you.

You just need to realize you are not using the correct sewing machine and needle. You need to use a 135×17 needle size 22. These needles are like nails and will penetrate up to 3/8” thickness of canvas. 

You also need a walking foot industrial style sewing machine to hook these needles into. Once you have the right sewing machine and needles….your sewing project will come alive.

How to Sew Thick Material and Multiple Layers by TuffSew

how to sew thick material

TuffSew here, your heavy duty sewing machine supplier. Whether you sew because it’s your hobby or your livelihood, it’s important to continue to learn different concepts and techniques along the way. 

Sewing begins to be a challenge when you decide to start tackling multiple layers of material underneath your presser foot. After reading this article, you should be better suited to handle situations when you must sew thick materials.

First you need to ask yourself “What type of sewing machine am I working with?” This is extremely important because every sewing machine has its limitations. If you are using a regular household sewing machine, the following 3 tips will help you:

1)      Do you need all that additional layer lining? Probably not. Cut off the excess (especially for side seams) but make sure not to break the actual stitching.

2)      Use the largest size needle acceptable for your sewing machine. Usually a size 18 or 19 needle will allow you to penetrate the multiple layers more effectively.

3)      In situations when you are breaking needles –maybe you are sewing a strap for a purse- use the hand wheel alone.

Those tips didn’t help? Still breaking needles? The problem is not you or your domestic sewing machine-it’s the capabilities of the machine. It’s time for you to start looking into more of an industrial grade sewing machine. 

Portable walking foot industrial strength sewing machines will stand a much better chance of completing your thick sewing projects. 

We recommend our TuffSew Straight Stitch machine, you can view it here http://www.tuffsew.com/straight-stitch-industrial-walking-foot-sewing-machine. Here is a video with more information on this type of sewing machine:

To go over the details of the above video. Walking foot industrial strength sewing machines will help you sew thicker fabrics because:

1)      You can use larger needles- up to 22 or 23
2)      There are “grips” on the walking foot and feed dogs, which help pull the heavy fabric through the sewing process
3)      You can use nylon thread and thicker weighted thread in general- giving the stitching in your final project much better strength and life duration
4)      More power- more RPM’s and torque equals better results when sewing heavy fabric
5)      More durability- all metal parts and cast iron construction will give you a machine that lasts much longer than plastic parts and construction
