A few things I did differently. I didnt cross the straps in the back...oops! I also made the straps a little wider than suggested. I cut some extra fabric from the bottom and serged the raw edges, but didnt turn up the hem. Its still cute and decorative. Also, when I sewed on the elastic thread, I simply turned the fabric and continued sewing the next lines. This saved on thread, and time. Isnt it adorable?
