This weekend my daughter and I found our way to the local Jo-ann fabric store. We found Pre-Smocked Sundress Shirred Fabric. The lady at the fabric cutting table gave me a measuring tape to see how big around Emma's chest was. We took it home the fabric; washed and ironed it. Then I simply sewed the two cut sides together and hemmed the skirt. Done!
We are going to put straps on the dress. But on that shopping trip Emma and I couldn't come to an agreement one what the straps should be. :)
I did find the official directions on Jo-Ann's website. (I'm not big on directions but for those who are :) )
