She always used cotton sheets for her backings for a few reasons:
- They were relatively inexpensive
- She could get them the size for the quilt she was making
- She had no extra seams to quilt through
- The sheets were 100% cotton
I cut off the elastic from the fitted sheet and opened up the corners and I will be opening up the top edge of the flat sheet. I will also be opening up the pillowcases for some of my smaller pieces or using them for sleeving on the quilts. I got the sheets on sale so I have plenty of backings for a great price.
Now I just have to decide how to lay out the quilts to maximize the backing fabric.
