Ruffle Butt Onesie

I used this tutorial from Crap I've Made to make a onesie for my friend who had her baby in April. I used a  red fabric with white polka dots and think it turned out super cute. Next time, I'll definitely set up the serger though!
Apparently I didn't get a picture of the actual ruffle butt part, but you can kind of see the ruffles peeking out from the side in this picture.
