icandy handmade has some incredible tutorials!!!! You need to go over and spend a couple hours looking through their site! I'm loving this refashioned shirt that looks like it ties in a bow in the front!!!! GORGEOUS! It's made from two t-shirts!
Also, make sure you check out their series of Fun in the Sun (dress)! Lots of great inspiration on summer dresses!
See the Tied Bow Shirt tutorial.
