I quilt as an excuse to buy fabric. But I donate fabric to my quilt guild, so that "justifies" it. And I get to see the fabric eventually become a quilt.
I once bought a fabric because it was on sale for a ridiculously low price. I didn't really like it, so it was donated. After many 'ugly' fabric comments, one of the quilters used it as a backing fabric. It was stunning!
