Thanks for the compliments.
I chose indoor/outdoor fabric because I'd be walking on these rugs, and I thought cotton may wear out quickly. They aren't hard to make, just time consuming because you can't stitch quickly, and you have to stop every 3-4 rows to press flat and let cool.
It was easier than sewing with denim! Slightly stiffer than cotton, which help when folding and sewing the "rope"
joanns was pricier than the website i order from. I also was sent the wrong piece of fabric that is plastic-y. (they refunded and said keep it) It is waterproof fabric. Gonna try it.
