The only ones I have made that don't get used on beds or whatever, are small wall quilts. They're sort of artsy and wouldn't be large enough to use, even as a lap quilt.
All the rest of my quilts get used. My g'daughter has used hers for picnics, for beach blankets, and for her dorm bed. Her mom, my daughter uses hers for beds, for sofa snuggling, and for the beach also. I once made jeans quilts for the big boys in the family, and they (now in high school) still use them for everything including football games in northern winters. They live in Ohio. All of the family pets have their own and really use them constantly. It gives me a feeling of being appreciated!
