I have two sweaters in progress and that knit bunny. Do you think I’d manage to pick up one of those and remember where I am on it so I can finish any of them? Nope.
I really should just give up on sweaters for the time being and knit socks. They’re easy and I have them memorized (well, the basics anyway, not necessarily each individual stitch pattern), and it’s something I can come back to days (or, sometimes, weeks) later and not feel lost.
