How To Sew With Waterproof Fabric Using Patterns

Sewing waterproof fabric can seem like a daunting task, but with the right tools and some basic know-how, it can be a breeze. Whether you're making a raincoat, a tent, or simply want to add a weather-resistant layer to your piece, sewing waterproof fabric is an essential skill to have.

How to Sew Waterproof Fabric

The following steps will guide you through the process of sewing waterproof fabric.

Step 1: Prepare Your Fabric

Before you begin sewing, you'll need to prepare your waterproof fabric. This involves washing and drying it to remove any excess oils, dirt, or chemicals that could interfere with the waterproof coating. You'll also want to press it with a warm iron to remove any wrinkles.

Step 2: Cut Your Fabric

Once your fabric is prepared, it's time to cut it to the desired size and shape for your project. Use sharp scissors or a rotary cutter to minimize fraying.

Step 3: Use the Right Thread and Needle

When working with waterproof fabric, it's important to use the right thread and needle. Look for a heavy-duty, water-resistant thread such as nylon or polyester. For needles, choose a sharp, heavy-duty option such as a denim or leather needle.

Step 4: Pin Carefully

Pinning waterproof fabric can be tricky because the holes left by the pins can create leaks in the fabric. To avoid this, use binder clips or Wonder Clips instead of pins. If you must use pins, place them in the seam allowances and be sure to remove them as you sew.

Step 5: Sew with a Waterproof Seam

To create a waterproof seam, you'll need to use a seam tape or seam sealer. Simply apply the tape or sealer to the seam allowance before sewing. Once you've applied the tape or sealer, sew the seam as usual, being careful to keep the edges aligned and the stitches straight.

Step 6: Test Your Project

Once you've finished sewing your project, it's important to test it to ensure that it's truly waterproof. You can do this by spraying it with water or by holding it under a faucet. If any water seeps through the seams, you'll need to go back and apply more seam tape or sealer.

Tips & Tricks

Use a walking foot to help your fabric feed evenly through the sewing machine.
Test your needle and thread on a scrap of fabric before you begin sewing.
Use a longer stitch length to help prevent leaks.
Consider using specialized waterproof zippers and snaps for your project.
Be patient and take your time. Sewing waterproof fabric can take longer than working with other fabrics, but the end result is worth it.

Sewing waterproof fabric is a useful skill for any sewist to have. With the right tools and techniques, you can create a wide range of weather-resistant projects that will stand up to the elements.
