I had some left over white onesies from a project I did last month, and I thought it would be cute to dress one up for baby H. I used old-school puff paint to create this necklace for her and I think it turned out so cute! Just slip a zip lock or any plastic inside the onesie so it doesn't stick together, and decorate with puff paint. If you don't want to free hand it, use a pencil or marker to draw on the onesie, then go over it with your paint.
It would also be cute with a painted bow tie, suspenders, mustache or even a sheriff's star. Makes a great gift, too! Simple and cheap, my 2 favorite things!
