Watch how to make them here:
1. Measure the dimensions of your pillow insert.
2. Cut the front piece of your pillow case from the shower curtain fabric. Cut this shape so that it is 1 in / 3 cm bigger than the dimensions of the pillow insert on all sides.
3. Take the rest of your shower curtain fabric and fold it in half so you can cut out two shapes at once. Cut your 2 back pieces, which should be the following dimensions:
WIDTH: width of your pillow plus 1 in / 3 cm
LENGTH: length of your pillow divided by 2, plus 4 in / 10 cm
4. Along the long side, fold the end over about a ½ in / 1 cm and iron it down flat to create a hem line. Fold the hem over again and iron it once more.
5. Straight stitch (or glue) all the way across the hem. Repeat this process on the second back piece.
6. You should now have three pieces: one front piece and two back pieces. Place the front piece down, right side up, then place the two back pieces on top of it, right sides down. Arrange the back pieces so that they are the same dimensions as the front piece when laying on top of it. They should overlap several inches.
7. Pin the pieces together all the way around the perimeter.
8. Sew or glue all the way around where you pinned. To avoid any awkward bumps or points, cut off all four corners of the pillow case.
9. Turn the pillow case right side out.
10. To help keep the pillow case shut when it’s on the pillow, sew two buttons into the bottom flap of the envelope pillow case.
11. Sew two loop shaped pieces of ribbon to the underside of the top flap of the pillow case.
12. Put the pillow insert inside the pillow case.
13. Now you have perfectly good outdoor pillows that are rainwater resistant! With one $10 shower curtain, you can make about 4 pillows. That’s four for the price of one!
