I finally decided to attempt crocheting one last night. Turns out these things are pretty easy to crank out... As for size, I was comparing it to a 3 month hoodie that we already have for her. This involved lots of trial and error and crocheting for an hour then pulling out rows of work, which would've driven my husband crazy if he had been home. But I think I was pretty pleased with the end result...
|5.5mm hook; half-double crochet|
Or a collar with some buttons?
I guess the possibilities are endless and I still have a ways to go before I get a sweater that's as cool looking as these ones (although I think those are knit and I'm way better at crochet so I might never get one as cool looking as those...).
