My old knitting project from 2018 finally got a second chance

I was halfway through a scarf for my sister in my old apartment in Austin when I dropped a stitch and the whole thing started to unravel. I just shoved it in a closet for years, feeling bad every time I saw the bag. Last weekend, I finally sat down with a crochet hook and fixed the mistake in about twenty minutes. What's a project you walked away from that was actually a quick fix?
