Welt Cord for Slipcovers: Which one works best?

Polyester Welt Cord for SlipcoversWhat type of welt cord works best for slipcovers?  My favorite is medium-firm polyester in size 5/32.  This cord (above) has a poly tissue-like core and wrapped with a braided cover. Here’s why I like using it for sofa, chair and ottoman covers:

  • Firm enough to keep its shape yet soft enough to bend around curves smoothly
  • Doesn’t shrink or pucker when you wash your slipcover  
  • 5/32 size is ideal for slipcovers and the slightly smaller 4/32 is good for pillows

There are many retailers and wholesalers who carry this type of welt cord.  For small quantities I recommend the retailer Sailrite and for large wholesale quantities I would go with Rowley.

Online upholstery suppliers often carry this type of cord, too.  Tip: sample before you buy.  I recently purchased 500 yards of “polyester welt cord 5/32” from an upholstery supplier and I was very disappointed with the quality.  The 5/32 size was wimpy and the core was mushy and flattened quickly.  Now I know not all poly welt cord is made the same way.

Cotton Welt Cord

Avoid using cotton welt cord (left) for washable slipcovers. The cotton fill is a bit lumpy and loosely covered with fishnet.  Another type of cotton welt cord is twisted like a rope. Either way, it’s mushy and flattens easily. Watch out, this stuff will shrink!





Slipcover Welt Cord: Self-Fabric or Contrast?


Choosing the color and fabric for your welt cord is a personal choice. Go with self-fabric for a classic look or get creative with a contrast color, texture and/or pattern.

I like using the same or similar weight fabric as my slipcover fabric for making the welt cord bias strips. For the cord, I get good results with this washable, size 5/32 quality. This cord has a poly tissue-like core and wrapped with a braided cover.  Find it at The Zipper Lady.
