You’re knitting a tuck or ridge in the bootie. This video may help give you the idea of the stitch. And this one may help too. It’s a very pretty and useful technique.
The videos were a great help and I’ve finished my booties. I made it harder on myself by knitting the tuck in the same main color so it took a bit longer to make sure I had picked up the correct stitch.
I haven’t knitted much in the past few years so I’m having to “relearn” what I used to know. And the new yarns and fibers are amazing!
I make life-like (reborn) dolls and love all the hand-knit layettes and outfits.
