The onesie is knitted in the round. In order to do the trim you will need several size 7 dpns (I use about 6) or a size G crochet hook. There are two ways to do the trim. I describe both in the pattern. Directions for appliques are not included. I find the patterns for appliques at www.crochetpatterncentral.com under “appliques” and “fridges.” The onesie is sized for 3-6 months.
