I've been working on something lately which, hopefully I'll get to share with you later this week.
But I needed to attach a Garter Stitch collar to a non-garter stitch edge and I found two helpful YouTube videos that I thought I'd share!
This one from Jimmy Beans Wool is great! This is the one that I actually ended up using.
and this one from Domiknitrix, which I found to be really clear and I like the way she describes the 'sad face' and 'happy face' as a way to see which stitch to go into!
Thank God for You Tube!
