Doll Hoodie Sweater.
Since I despise seaming, I adjusted the pattern to work it seamless. It was a cinch.
The pattern originally called for it to curl a bit at the hem, but I didn't like that look. Mine rarely stop curling when they're supposed to, so I simply did four rows of garter stitch at the bottom to prevent that. I got the idea from other people who had knit the hoodie. (I always like to look through "helpful pattern notes" before beginning a new pattern.)
My daughter's Bitty Twins are going to have a complete wardrobe overhaul after Christmas this year! :)
