I have a box like that too. At some point, I'd like to make a prairie point border for a big quilt. Yvonne made a flag wall hanging out of prairie points that is really worth a look.

Jan22: we had a demo on this technique at our quilt show last month. The demonstrator called it "disappearing 9-patch". It was a big hit and lots of people tried it out and said it was great fun to do this block.

Our quilt group's making lap size quilts for a nursing home and I used this technique. It went together in just a couple hours. Last nite I did the free motion quilting on it and tonite I'll finish it up with the binding. I previously made a twin size quilt for a friends son who is a freshman in college. Using many different fabrics in masculine colors I made a variable log cabin block (the center was much larger than normal) then I cut it in half, and in half again and mixed up the squares with several others, sewed them back together and it was a very stricking design. The kid was very pleased to get it for a graduation gift. Now I'm hoping it's not hanging out his window at college.

If you have any leftovers, I just saw the cutest apron, made from scrappy squares (nickels, I think) in the connectingthreads.com catalog.

Make sure you show us what you come up with!

The quilt top I just finished is based upon 4 inch squares + a 4patch. Let me know if you want me to scan the pattern.
