How about the Disappearing 9 patch? You can use whatever scraps you have, it can be scrappy and you can arrange the blocks into any interesting design that you want.
If you aren't familiar with the D9P, I'm sure you can do a search here and find lots of postings about it as well as photos.
Bonnie Hunter loves to buy 100% cotton men's shirts or large skirts at thrift shops or yard sales to use in her scrap quilts.
Have fun and let us know what you come up with
