I hope I succeeded! I tried to do a bit of serging, but a zig-zag is what you see. I hemmed the neckline and the sleeves, sewed up the holes, baste-stitched the neckline to pull the strings and formed ruffles. I then sewed the ruffliness in place, pulled out the basting stitches and this is what you have:
I wish I had time to add some ruffles to the bottom, but this needs to be going home with her tomorrow.
I used this technique found here at Obsessively Stitchy.
