Go for it! One thing that might help is using an iron-on patch on the inside first, to keep the fabric in place and more stable while you’re stitching. I did this for a security guard friend’s uniform pants a few times, since he’d wear out the inseams doing his rounds.

It's a 3-ply actually. I have the feeling the skewing is partly due to tension issues... I know my tension is all over the place while I'm figuring out how to knit in a way that won't ruin my hands.

There are several options for nalbinding stitches that look knitted to people who aren’t familiar with nalbinding

I'll have to look that up! I'm still figuring out how to pace myself to avoid fatigue and hand strain.

Probably a cowl. Mostly it's just practice since my tension is currently all over the place. It's been over 10 years since I knit with needles and I'm learning Continental to reduce hand/wrist fatigue.

See if you have a spinning guild in your local area, you might be able to get a de-stashed drop spindle. Maybe even some in-person lessons.

I ended up with waaaay too many stitches, so I ended up frogging it and casting it on correctly this time
