Cut Fabric. Fold the fabric in half, lengthwise and smooth so it’s even (if it’s not already). Cut along fold line so you end up with 2 pieces, each 1-1/4 yds. long. Depending on the width of your fabric (45,” 54,” or 60″) trim your long pieces to be 18″ each. Adjust if your pillows are different sized: 16″ for 16′ pillows etc. NOTE: I always make pillows to be the size of the pillow form with no room for seam allowances so that the pillow is nice and full.
Make first, narrow pocket edge seam. To make the pocket, fold one short edge of fabric piece 1/2″ (towards wrong side) and then fold over again 1 inch to make a double folded seam. Pin and sew close to folded edge (see first photo above). Tip: always use a long stitch length in home decor sewing – it will lessen puckering of fabric and sew faster.
Make second, wider pocket edge seam. Repeat folding and sewing on the other short end of fabric, except this time fold over an inch first and then fold 3″ to make a wide seam (this will show on the outside of the pillow and is a more finished, sturdy look). Again sew close to the initial folded seam, as seen in the second photo above.
Wrap pillow with fabric. Set pillow form in the center of the fabric and, starting with the wide seam, bring the end around form to the middle (1st photo above). Bring other side of fabric with the narrow seam around pillow, pulling fabric tight and smooth, keeping it even and overlapping it over the wider seam. Pin seams together, creating the pocket opening (2nd photo).
Pin raw edges. Smooth folded and pinned fabric with raw edges even and pin all raw edges (1st photo above).
Sew & finish. Straight stitch along both pinned edges, removing pins. Tip: remove pins before the sewing needle gets to them to lessen the chance of breaking your machine’s needle on the pin. Clip corners, turn pillow cover right side out and insert pillow form.
Repeat the steps with your other piece of fabric and you’ve got two new pillows for a few dollars in about an hour.
