When my boys were small they loved wearing the character socks (Batman, Spiderman, Looney Tunes, etc.) As they grew older or wore out a pair, I saved them to make a quilt. I'm going to use the socks that don't have holes in them to make a "wheel" pattern and use solid fabrics as the background. The socks with holes I will cut and use the good parts, sew together, and use as the binding. This would work with baby's socks as well - the lacy ones would be really cute!
