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.

What Tools Do I Need to Sew Canvas for Boating Projects

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. 

We strongly encourage you to use a machine with a longer 9” base-it will certainly make things easier on your when sewing canvas. To learn more about this sewing machine, please click on the video below:

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.
