I found a very simple and easy tutorial a few days ago. It was so simple that I wondered why I hadn't thought of it myself! And here it is!
I made the skirt 17" around without much thought, and 8.5" down. I made this one a bubble skirt. So I made it 17" for the length and folded it in half, then followed the directions as normal. Pretty cute don't you think?!?
WAYYYYY too big for a new born though. So big, that it actually fits Isabel (my 18 month old) perfectly. She wore it to the play gym on Sunday.
