How do you like scrap quilts? You can go and cut a 2.5" strip from all your stash items and use it in a pattern that calls for jelly rolls. Same thing with charm squares (5") or layer cakes (10")
I guess what I'm saying is make your own precuts. There's lots of free patterns out there, here's a great source:

You can make a controlled scrappy with a single color for the background or sashing to tie everything together. You can also just cut a strip from all your reds, or blues etc. It's amazing how different hues of the same color look great together!
Another idea is look for a single block you love that has 2 or 3 colors.

Use the same background fabric on each block, but a different focus fabric, then sash it!
