I'm fairly confident at sewing but my one attempt with something stretchy was a disaster. Inspired my the sewing bee and DDs too short tshirts I really fancy trying to turn them into dresses. I've seen some tutorials where you use non stretch fabric but was hoping I could reuse either a dress of hers or a tshirt of mine / DHs.
So will a zig zag work to join them, or is a double needle necessary? I'm not sure if I have one but probably do, just a little scared!
