I've just made a dress for my 3 year old DD out of an old t-shirt of DH's and some jersey material for the sleeves and a ruffle at the bottom. It was a nightmare! The material kept stretching as it went under the foot and moved around and basically did whatever it liked. I've finished it, but the quality is appauling. I've got a couple more dresses with similar material planned and I need to know what I did wrong. Any advice would be gratefully received!
