This is new to me. I mean I never thought it could be a substitute for fabrics to practice sewing. But it's a good idea as beginners will not waste any fabrics when cutting it wrong. Though it's a bit harder to use that. But anyway, the result is quite good and soon you'll be using fabrics for your next projects. Good luck and God bless..
