I guess these are the newest "big thing" right now huh? I just watched a different video on YouTube, and there is a somewhat ... shall we say... spirited discussion going on about whether the pattern can be copyrighted. Actually it seems just like the coiled fabric bowls I have made in the past, just keeping it flat instead of tilting the roll so that it forms into a shape. And some enterprising company (Bosal, I believe) has started selling the rolls of 2.5" batting so that you can make them with jelly rolls. My local shop has also scheduled a class on the rugs. Funny how must-have items and newly-discovered techniques just keep circling around and around....
