When the onslaught on newborns on the way, I dug into my stash and came up with some cashmerino aran wool and adapted a Debbie Bliss pattern for a baby raglan jumper to knit top-down. The whole thing is down in stocking stitch on purpose so that the neck, hem and cuffs roll.
The pattern is a little wonky in that the sleeves are relatively long compared to the length of the body. These pictures are actually from my second go. The first one was in newborn size for my nearly-bursting co-worker, Sahera. That one was done to the patterns numbers and looked really short. The pictured one (done at the 12-18 month size) went home with Ms. Walker for her niece and I purposely lengthened the body a little to balance it out.
