That's so funny, the blanket I'm just finishing up is similar to yours! I have a baby blanket with three cables, with a sead stitch border. It'll be done soon. I'll take a picture and share. I guess great minds think alike. My cable is just a simple braid, yours looks like it has three stands, I would love to learn how to do that, is it similar to a regular two strand cable?
thanks for sharing again!
