Weaving for me. I've even picked up a small "pocket" loom, that's about A5 paper size that allows me to practice tapestry techniques on the move. This summer I plan on taking it to parks, brewery patios, etc.
Weaving looks like fun!
One of the things I appreciate about knitting is how accommodating it is as a hobby. If I want to really focus on knitting, I can choose a project that uses a lot of complex stitches, cables, etc. If I just want to zone out and feel like I'm making progress, I can choose a simpler pattern that just does the same stitches over and over.
If I want to make something large and intricate, I can pick a pattern that uses multiple colors. But if I want something portable, I can pick a pattern that just needs a single ball of yarn and a single circular needle.
This is a really good observation.
Lately, knitting has been scratching this itch for me.
