How do you sew a folding matress pad cover?

To sew a folding mattress pad cover, start by measuring the dimensions of your mattress pad and cutting two pieces of fabric accordingly, adding extra for seams. Sew the fabric pieces together, leaving one side open for the mattress to fit in. You can create a pocket or use a zipper for easy removal and washing. Finally, finish the edges with a serger or zigzag stitch to prevent fraying.
