well, now that you have asked....I just bought three bolts!
I will use it for everything.
I will back my kids and grandbaby quilts with coordinating fabrics, but will back my own with this, as I am planning on doing some of mine, as summer quilts.
I will use it for table runner backings, wall hanging backings, topper backings, line tote bags with it. I think I will even do a country looking quilt and put some on the front. Maybe some hand embroidery.
I will wash and dry several times first though! :D
