I know what you mean about "outdated: but when we stop to think about the retro fabrics, the 30s fabrics, Civil War reproduction fabrics, how can we call a quilt outdated when we are copying fabrics and designs of so long ago.
Your outdated quilts will be so welcomed and comforted by the people who are gifted with them. I can think of nothing better for you to do with them. And, as you mentioned, think of all the practice you'll get by finishing them. Good luck.
