I've taken to making lots of small quilts lately. They are usually around 16 x 20. It's easier for me to find spots on the wall to hang them than it is to find places for larger wall hangings.
A good source for small/miniature quilt ideas and patterns are the books by Kathleen Tracy. They can be found on her website, which also has several free patterns for download....
