Embellishing onesies

You can do this in one of two ways (actually, there are more, but whatever...):

You can search through your scrap material and cut said fabric into some sort of recognizable shape and stitch it on.

Or you can swing by a store that sells iron-on embellishments, pick out one that rings your bell, and get to ironing.

Either way, your cherub is cute and you look cool.
