Knit fabric: Light to medium weight jersey recommended. AMOUNT NEEDED: 0.5 yards for Preemie and Newborn. 0.75 yards for 0-3M to 12-18M. 1 yard for 18-24M to 5-6.
Ribbing fabric: similar weight to main fabric. Rib knit or stretchy jersey works well. AMOUNT NEEDED: 0.25 yards if NOT doing mitts. 0.5 yards if DOING mitts.
Zipper for front. I recommend a zipper by the yard in size #3 or #5. You can also buy a zipper and trim the bottom to length. You will need zipper stops for the top if using a zipper by the yard.
