I finished the singles and got a bobbin's worth plied. It's drying right now.
I think it turned out very well. This is about 168 yards and I still have at least this much left to ply. I do have less of the black singles, so will take the extra purple/yellow singles and ply it to use for heels/toes. If there's enough I'll Navajo ply it. If not, then just two ply.
I got the rest of the Log Cabin singles ready for plying and will get to that tomorrow.
