Just curious as to how many of you do this, or vice versa (crocheting with a knitting needle). I misplaced a DPN whist making a thumb for a glove, and I’m at work with only a crochet hook to help. So far, so good. 
Lol, I probably would if I have to, but for now, I have a few dpn sets that have a few odd colors in them… Yeah, like the dark blue with the pink… yeah…
