Double Thick Tunisian Potholders

I’ve made a few of these double thick tunisian potholders. They are made the same way as the regular crochet ones. I found this this  free pattern HERE. The only thing I have done differently is I have made mine using the tunisian simple stitch instead of the tunisian knit stitch.  They have turned out amazing.  The patter n doesn’t give how many rows to stitch up but for me it’s about 12 before I can seam it up.
