I am using flannel for the backing of a quilts. It's a memory quilt. It has 8 inch squares of different fabrics with a 4 inch denim border.

I read on here that someone used LL Bean flannel sheets for their backing. I ended up going that route because I couldn't find fabric in the right color or size.

I am pre-washing and drying (on high) the sheets prior to putting them on the quilt for possible shrinking issues. Should I was them more than once? If so, how many times?

Thanks in advance for your help. :)

I've never used flannel sheets but I wash my flannel yardage twice just to be sure.

Yes, wash it twice. You don't want to take any chances on shrinkage after the fact.

sounds like you need to wash it twice

Thanks! I was planning to do twice. Just didn't know if that was enough.

I have used LL Bean flannel sheets on the bed. The first washing should be enough to shrink them, if they shrink much at all. I haven't had a problem with them shrinking at all.

If they are sheets I would think they are already pre-shrunk, I wouldn't be too pleased if my new queen size sheets shrunk in the wash!! LOL But washing twice can't hurt it, and is worth making sure anyway!!

Cheers!
