My first try - which is sometimes a wash - turned out pretty good. It is a little big, but cute because Ava doesn't have any long skirts - her shirt is pretty big too actually. I could totally rig up one of these for myself - oh, oh or a tiny matching one for Lilly!
Here are a few other patterns I think look very, very easy -
Popover Sundress from Oliver + S
32 minute messanger bag from Amy Smart via a guest post on Design Mom
Fabric Flowers from the Idea Room
Adding a Ruffle to a Hoodie from the Idea Room
Ruffle Butt Onesie from Ucreate
Vintage Baby Hankie Dress or baby shirt from Trey and Lucy (omgosh so adorable, so easy!)
