I found this pattern and tutorial here! It is fun to make, and easy to follow. "Smashed Peas and Carrots" has a bunch of nifty little crafts and stuff.
Give this a try for a little one you know! It's for ages 6-12 months. However, as baby gets bigger, this little dress can become a fun little shirt for her. The next one I make I want to try to add a little lace or something at the bottom or a little sleeve of some sort, idk, we'll see.
