The sleeves are padded with batting. A tip: cut your batting slightly smaller than your fabric to reduce bulk when you turn over the fabric. I use my seam allowance as a gauge. And to keep it in place, I used the adhesive spray like the one below which you can get at any quilt shops or crafts shops.
