How to Sew Long Zippers Using Matchup Marks

Item # X-HT-300337

Sewing long zippers on large assemblies can be quite tricky. It’s important to use matchup marks to line up the first and second half of your zipper while sewing, otherwise your fabric application may not zip up evenly when you’ve finished your project. In our short video, we’ll teach you how to install a zipper accurately using matchup marks to ensure both sides of your zipper are sewn on consistently. This applies to all types of zippers, including coil and VISLON®.

Basting our zippers

Matchup marks are almost always required when sewing very long zippers, like those found on our Sailrite® Genoa Sleeve Kit, which is a long fabric sock with a zipper used to protect a furled sail on your boat. To mark on our fabric, we chose to use the small yet versatile Chalk Pencil Cartridge Set (#121669), which has a variety of chalk colors so you can choose the color that will show up best on your colored fabric. We'll be attaching our YKK® Continuous Coil Zipper using the handy Seamstick 3/8” Basting Tape for Canvas (#129) and then sewing the zippers with our Ultrafeed® LSZ-1. We’ll also share a few helpful tips and tricks to keep in mind when installing zippers on future projects.

Follow along with our short video to learn how to correctly baste and sew both halves of your zipper, one side at a time. Learn how to correctly add matchup marks to guide your sewing and ensure your project turns out perfectly.
