I like the crayon quilt idea,,too. Since you only have FQ of the solids, it would be a good use of that fabric. Since you have 3 yds of stripes....you can do an awesome border treatment and then use it as binding against a final solid border from your stash. Lots of colors from the stripes to chose from. I don't know if you like PP but you could make a couple of block from a PP pattern for corners of quilt etc. ideas are endless.
