Triangles and Squares

I have been reaping a great deal of these half-square triangles from recent projects. Add to those all the squares that I've cut from ends of strips and I have the makings of ... of ... well, something. I just don't know what. I'm going to need to use some of what I learned in Roberta Horton's class about value. The colors sure don't go together. I don't think the sizes mesh either. Hmmm...this is going to take brain power to figure out, and right now I have none.
