Making 2 quilts for my granddaughters, I wanted to use bits of fabric from a quilt I'd made for my son ~35 years ago. His quilt had fallen apart (novice mistakes) and I'd saved some fabric. I worried that this old fabric wouldn't wear well, so before cutting the pieces, I ironed pieces onto very lightweight stabilizer. These small pieces are a bit heavier than the surrounding fabric but after sewing and quilting, there isn't a noticeable difference.
