Great job Dorothy!
I forgot to add that when I used wash away on the bottom I hooped 2 layers, sprayed with Taylors quilt basting spray and 'hooped' the towels this way. There is almost no way to hoop terry cloth in the hoop. I didn't use any spray on the top to hold the wash away.
Also thanks Maryb for the double thread idea. I shall try it next time!
