Finally I decided to just pick something and stick with it, even if it might not be the most fascinating project ever. I have 100g of various DK/Worsted weight yarn that I'd been meaning to knit into Salomas Slippers but just never got around to, so I figured now was as good a time as any.
Not the most challenging knit ever, but they're fast and fun, so I'll take it. And I'm very amused by how they look with no foot inside.
They're slightly too small - I knit size medium and should probably have gone for a large instead, but I wasn't sure I'd have enough yarn. I have PLENTY so now I'm considering whether I should frog the first one and knit a pair in size large instead, or if I should just knit the second one as medium as well, and pass them on to somebody with smaller feet! ;)
