Supplies: fabric scraps, (particularly upholstery) sweater or cardigan, sewing machine, scissors.
Begin by cutting out different patterns to stitch onto the sweater. I created eight arrow ends, 2x7 inches, and one diamond shape for each side. Once you've cut out the pieces, pin them in a pattern onto the sweater. Lastly, top stitch them in place. A top stitch will give it a very messy look, allowing the ends to fray.
Hope your weekend ends on a lovely note.
