Then I made a matching bow for her hair that can clip onto a headband like in the picture or just in her hair.
Here is the link I used to make the dress: http://www.maubys.net/2010/06/fat-quarter-fun-pre-toddlertoddler.html This website has some cute stuff that is pretty easy to make.
I think it turned out pretty cute and I can't wait for her to wear it. The nice thing about a pillowcase dress is that when it gets too short, you can throw some leggings under it. So this should be in her closet for a while!
