After my friend Melissa saw Catie's cute apron she asked me to make one for her little Emily which I was more than happy to do. Her's turned out so cute and I hope she's happy with it.
I also had a couple people interested in making an adult sized apron so I finally managed to track down some measurements, they're listed below. If you're looking for a tutorial you can find it here, it's for a child's apron but the adult will be the same except for sizing.
Front - 23" sq
Back - 25 1/4" Sq
Bottom Trim - 2 1/2" x 26" - cut two (back fabric)
Neck Strap - 3" x 23-25" (back fabric)
Waist Ties - 3" x the width of your fabric - cut two
Pocket template - cut two (one the front fabric, one the back)
