Recycle your old jeans into this two-tone denim blue fish. It's real quick and easy to make, and it can be sewn by machine or by hand. Denim scraps is all you need!
Use a wide area to make your fish body on your old jeans, like the bottom of the legs. Sketch a simple and easy fish body about 9" X 5" onto your denim. You are more than welcome to copy, paste, and use my silly little sketch, but I think you can probably do better than mine. LOL
