Here is a real mash up of yarns in a pair of socks - five different balls of leftovers. Since two of the stripes are so varicolored, the stripe pattern really doesn't show. So that part is a fail. But the real aim here was to use up some small balls and the overall effect is warm and pretty.
The pattern link is here. I only used the pattern for figuring out how to get the stripes going. Not wanting to do any heel shaping, I opted for an afterthought heel.
