I just bought a box full of "quilting fabric" at an online estate sale. Fortunately, I didn't pay much for it. However, now I have about 30 yards of mostly 1 yard cuts and a few 2 yard cuts of polyester (I think) seersucker. (I haven't done a burn test, but it feels like polyester.) It's still in the box and bags it came in about 8 years ago. I opened one of the bags that was labeled 1 yard of white, but it was 2.5 yards of a floral, so I'm not sure how much yardage is there. It would make great kids (probably girl) quilts if it wasn't polyester.

Any suggestion of what to do with it (including gifting it to a charity)?

Polyester and cotton/ polyester blends actually make great kids quilts. They hold up to lots of wear & tear, laundering. Make forts- have picnics, great play quilts. No reason to not make kids quilts with the fabrics

I’ve use poly in quilts with no issues.

I made quilts for my dog's bed using polyester . . . very durable. I made a rag quilt with denim and polyester for the car . . . it was also durable and comes in handy to sit on at the park, to wrap around items I'm moving from place to place and when I had a flat tire, it saved me from getting so dirty. Polyester makes some great outdoor quilts and utility quilts. They're not quilt show quality but many enjoy them.

Are you talking about 100% poly knit? Or, cotton poly blend? I think MaryMo is talking about the poly knits. If you have cotton poly blends, I treat it as regular fabric all the time with no problem. Great stuff for quilts.

The first quilt I made had a polyester backing.
The LQS had recommended I use poly, because it was king size, and it would slide better.
Otherwise, bulky, weighty, and cotton backing against the sheets, it would be hard to move.

It seemed odd at the time ... but with use, I was sure glad I listened to them!

How about giving to a group that makes the little girls dresses (pillowcase dresses I think they are called)?

Make charity dresses with the seersucker, and pillowcases with any smoother fabric. There are always shelters looking for pillowcases...

Polyester was "in" during some of my Mom's quilting era. Those quilts wear like iron. I don't think that ever wears out or fades. Use any pattern you like!
