here are the steps to sew a pillow cover:
1. Prepare the fabric: Wash and dry your fabric.
2. Hem the short sides: Hem both of the short sides (the ones that are 21 inches long).
3. Fold and sew: Lay your fabric down with the right side up. Fold it in half so that the hemmed edges are together. Sew along the two raw edges.
4. Clip and flip: Clip the points off of the four corners, being careful not to cut through the hem you just stitched. Flip your pillow cover right side out.
