I found one kind of like this online, and drew up my own pattern to try to copy it. It took a little longer because of the 3 yarns twisting, but I really like the 3-color ones.
Just finished one more as the weekend winds down. I found some music note charts online, and modified them to make this one. It was a lot of stranding, purple behind white, and I'm just not so happy with the way it shows through in places. Maybe I'll try it with heavier yarn next time.
I decided to try a plain one when I found this jewel toned variegated yarn. This one was quick and easy, but it's made with worsted weight yarn - a little tough using size 2 needles.
