I started to learn how to knit but I kept doing yarn overs the wrong direction because it's a bit different from crochet's yarn over, and then I had to put my scarf aside for a few months and when I had time again I was terrified to mess it up because I couldn't remember which one was knit and which was purl, and I was in a different country from the person who started teaching me, so I never learned how to bind off... Someday I will figure it out. Until then, I must be content with being awesome at crocheting.
