If you don't sew, you can also try using the Heat N Bond hem tape. You basically "tape" the fabric together by heating it with an iron.
If you do this, then you can make fleece pads: two layers of fleece with either batting material or Zorb in between. I've not used the hem tape on fleece (since I sew), but it should work.
