Things You'll Need:
- Closed cell polyethylene foam, 1 inch thick (1.7-pound density) and cut to 8 by 24 inches Outdoor-quality vinyl fabric, 20 by 28 inches Sewing machine Heavy-duty thread Denim needles
-
Step 1
Fold over the vinyl with the right, or patterned, sides pressed together. Sew a 5/8-inch seam along the short bottom edge and then up the long side. Take a few reverse stitches at the start, corner and end of your sewing line to secure the stitch.
-
Step 2
Turn the vinyl right-side out. Run your fingers along the inside edges to push the seams and corners outward.
-
Step 3
Insert the foam rectangle into the vinyl pouch. This should be a tight fit that will force the foam to compress slightly, but not so much that the thread is exposed or breaks.
-
Step 4
Fold in the ends of the vinyl, creating a seam, to close the end. Pin the ends together, if needed. Sew along the edge to secure the foam inside. Use as needed and wipe clean with a damp cloth.
