I have a question I hope someone can answer. A long time ago, I knew a lady who had made a beautiful quilt but because she had used a cotton covered polyester thread (the common Coats & Clarks), the quilt literally started to fall apart. She mentioned to me at that time that the reason that happened to her quilt was because the polyester in the thread was much stronger then the cotton fabric and that she should have used a 100% cotton thread. Even though she backed it with an interfacing - didn't help. Now I just ordered some really neat thread that is the color of the thread they use for jeans and would be perfect to use for a jean denim fabric. One potential problem - the thread is polyester but the vendor I purchased the thread says it was thread used specifically by a jeans manufacturer to sew jeans. I was wondering if using this heavy-duty polyester thread just might cut through the 100% cotten jeans denim fabric. I am going to be making some totes to sell and I sure don't want the totes cutting apart after I've sold them. That would be a disaster. I'm thinking I'm going to have to actually make a tote and test it myself - but if someone else has had some experience in this area I wouldn't mind going that route either. Thanks! Laurie

For denim Sandra Betzina recommends "good quality polyester upholstery thread on top if the seams will be under stress."
The jeans thread -- yellow stuff -- is used for top stitching, right? Not on the seams that get the stress.
It seems like it would have to be some tough darn thread to cut through denim. It's not the same situation as the cotton used for quilts.
When I've worked with denim I've used Gutermann's polyester and it has lasted as long as the garment.

Thanks Dorothy! I was hoping someone would say that! Sometimes it can get kind of tricky.

I've made a lot of jeans and most of them I used polyester thread. I just use the same thread throughout, not changing depending on whether it's a seam or topstitching. No problems.
