1. Mark the size of the pillow insert on the rug using duct tape stuck onto the rug as a guide. Cut cushion front covers the same size as the pillow inserts and do not add a seam allowance.
2. Cut out along the center of the duct tape and through the rug with the Amplify scissors.
3. Adding extra duct tape to the back of the cut ends will help to keep the rug from fraying.
4. Set the machine up for sewing heavy fabrics including the use of a needle suitable for sewing canvas or denim.
5. For the backing, cut a piece of canvas or denim the width of the insert by 1-1/2 times the width of the insert. Cut length in half. For example, if the pillow inserts are 20"x20", cut fabric 20"x30". Then cut into two pieces of 20"x15". Hem one long end on each piece of fabric by folding twice to the wrong side and stitching.
6. Pin the canvas to the rug with right sides together and with the hemmed ends towards the center back, and sew through all layers. If the rug is too thick to pin, consider using binder clips to keep the layers together while sewing.
7. Clip the corners for a neater finish and turn the cushion cover right side out through the opening at the back. Depending on how much the rug frays, you may want to leave the duct tape on.
8. Push out the corners with a blunt tool and insert the pillow into the cover through the opening.
