I didn't use a patter, just kind of traced the top of a sundress she had and used that for the bodice. For the skirt I just gathered two rectangles. I wanted to add a splash of color, so I bound it with strips of another knit. I only had a tiny piece it, so I had to cut it vertically, not horizontally like i normally would with knit binding. But because this was a four way stretch, it worked pretty well.
Lastly I had two small pieces left, so I made a sash. She loves it and I think it came out pretty well. She really needs some more summer dresses, so I think I will make her another one.
