This bodysuit (or onesie, if you prefer) has the look of a classic cardigan with the diaper-changing ease of a snap placket at the crotch. The pattern fits sizes newborn through 4t, and the newborn size will fit most 18″ dolls. There is an option for a faux undershirt, and a short sleeve or long sleeve with cuffs.
Genie choose to make her little man’s with comfy cotton lycra from the Peek-a-boo Pattern Shop. The stripe is from the Knit Basics collection (Yarn Dyed 3/8″ Gray & White Stripe, and it was a lovely fabric. I wasn’t sure what to expect from a bargain line of fabric, but this is a nice weight, soft, and has great recovery. The blue can be found here.
