Hi, I've done this before and I use two types - the melt away and the water soluble. I put the water soluble in the back, and then the melt away in the front. The melt away helps the towel stay fluffy while holding down the stitches. The rinse-away is nice because it doesn't pull your stitches out. I've also used adhesive for towels and pinned the melt-away on top out of the embroidery field. That works too. :) Have fun!
