Tips for Inserting Zippers Next To Welt Cord

Zippers next to welt cord.  How are you inserting zippers next to welt cord in pillows, cushions, and bedding?  Do you ever wonder if yours are sewn well enough?  Do you ever struggle with the size or type of zipper you should use?  In this blog, we’ll focus on two types of zippers next to the welt cord: regular zippers and invisible zippers.  Once you get the hang of inserting these, you’ll be zipping along with no trouble.  Let me help build your confidence so you can build your sewing skills.

Regular zippers next to welt cord

This may sound like a no-brainer because many of you are comfortable inserting regular zippers next to welt cords in pillows.  The tip I’d like to share with you is the size of the flap you use to cover the zipper.  This flap should not be so large as to cover the welt cord.  And it shouldn’t be so small that the zipper shows.  The flap should touch the welt cord.  You may need to play around with the flap size based on the fabric weight, the size of the welt cord, or how full you fill the pillow.

Invisible zippers next to welt cord

How are you doing sewing zippers next to welt cord? Based on the number of calls, emails, and requests I receive from you, this is a zipper technique many of you are fearful of and want more assistance with. Let me share a few tips on this technique to help you.

Tip #1

It is possible to sew too close to the invisible zipper teeth. When this happens, it will be difficult to open and close the invisible zipper. If you accidentally sew over the teeth of an invisible zipper, it won’t work, so it’s best to start over with a new zipper.

Tip #2

When sewing an invisible zipper next to welt cord, a drapery-weight fabric, an invisible zipper size #3 works well.  However, for heavier fabrics or when using lining and interlining in your pillow projects, moving up to an invisible zipper #5 is a good idea.  This is due to the turn of the cloth.  The heavier the fabric, the larger the turn of the cloth will be, which will then bump into the zipper teeth, making it difficult to open and close the zipper.  Lastly, you’ll want to use invisible zippers for home decor use.  Zippers for the clothing industry are not intended for home decor use.

Tip #3

When you sew an invisible zipper next to welt cord, the cord is sewn to the pillow first, of course. Be sure the seam join of the welt cord or the decorative braid cord is not along the edge of the pillow or cushion where the zipper is sewn. As a habit, I always place this join in the lower-right corner of the project.

  Tip #4

I’ve saved this tip for last because I want to be sure you remember this one.  And this is your pass to freedom.  It’s almost impossible for the invisible zipper to be right up to the welt cord.  But this is okay.  The welt cord will cover this once the project is completed.  Really, it is.

Tip #5

Are you a visual learner?  Look at this YouTube video I made to see how I like to insert an invisible zipper next to the welt cord.  Watch the video to get the idea.  Then, you can start and stop the video as you sew your invisible zipper next to the welt cord.  Watch the video here.
