'Quilts on the Floor' is quite an interesting book. The author uses some different techniques though. She paints quilt patterns on canvas which would definitely be durable on the floor. Also uses a 'Decoupage' technique with fabric strips; 'glues' them into a pattern which would also be very durable. What a way to use up some of your stash!
I've made an Aunt Phillys toothbrush rug - - - nearly 30 years ago and I still use it. Throw in the wash when needed. Love it and would much rather do that for a rug then glue strips of fabric onto canvas. Just my opinion. . .
If you make a quilt rug, please be sure to share pics!
