Writing CSS always seems like a disproportionately large amount of work for a very small and unreliable result. I suppose no one expects people to actually type the stuff in a text editor; we're all supposed to be using AI code generators or something. Sigh.
Be that as it may, there are some instructions for knitting the Traveling Stitch* on my website now. They are very much not optimized for mobile. But the pictures do get bigger if you click on them.
[* I still think of it as a Fake Decrease, and I'm pretty sure I've seen it called Twisted Stitch, which seems very confusing because how do you distinguish that from stitches knit through the back loop? It's also a Mock Cable, I guess. Is there any kind of standard terminology for any of this?]
