Maybe. I don't remember sk as in next sk meaning anything in crochet lingo but it's been quite a while since I followed a crochet pattern. I was wondering if it might be a typo, especially with nextsk run together as it is, sometimes that happens, and if the typing is done on a device it's so easy to do. Also the see patternnotes (again run together, device typing?) seems to indicate something different might be going on. I don't know. I wish I could at least see what the project looks like. The closet I could come was Button-Cuff Boots
When I type on my phone or tablet it is really, really challenging.
