I have some Japanese kanji prints that I bought simply because I thought they were awesome, but have no freaking clue what to do with them.
But I also have favorites that I bought that are going into the two quilts I'm making for myself (a scrappy purple cathedral quilt and a Kittie---my favorite band---t-shirt quilts). Maybe that's the solution: use the fabrics we really, really, REALLY love for quilts for ourselves. :)
