This pattern requires 2 colors but doesn’t even use up a whole skein in either color. You could choose to do it in one color if you would like but this is actually a pretty easy pattern to complete. The most difficult spot is transferring loops from a loom to a stitch hold and back to a loom. As most things there are other ways around it if you don’t feel comfortable with it. I do tell you how to adjust for bigger, but would not be a 100% on smaller.
