I used the tutorial found here to make the shirt which was pretty easy.
Then I used the Baskets & Blooms and Flower Folds Sizzix dies from Stampin' Up! to make the flowers for the girls hair. I cut one flower out of white felt and one out of fabric for each size, poked a hole through the middle and attached all the flowers with a rhinestone brad. Then I cut a small slit in the felt on the bottom flower to slide the clip under the felt and brad which is a pretty tight fit so it shouldn't come undone. Easy and no glue!
