To complete the Racing Horse scarf and hat set, I also knitted a pair of fingerless mitts. Unlike the first two projects, the mitts are not double knit. They are only one layer with a smaller version of the checker-board.
I used a free-pattern that I have used several other times. If you would like the pattern, it can be found on Ravelry (here). This is a fabulous pattern and can easily be altered to match any project. I have used it to create a pair of speckled mitts, and a solid purple pair.
