Have just finished a quilt top using the Bali Pops 2 1/2" strips and wondering how to continue. I've pre-washed my border, backing (flannel) & binding fabric, since it was yardage and have pre-soaked the batting but, of course, to keep them accurate, the strips weren't pre-treated . What do you do when using pre-cut strips?

I didn't prewash the fabric I was using for the jellyroll quilt. I haven't go it all put together yet, so hopefully everything turns out okay.

I didn't prewash my jelly roll either. But I do prewash flannel. Didn't use both on same quilt though.

Didn't pre wash my jelly rolls and didn't prewash my backing fabric. They were both cotton though.

I wouldn't prewash a jelly roll. That would be a mess when it came out of washer.
