The edges that look like binding... are not binding!! Its so super simple... those are just the edges of squares that wrap around to the back...best thing is NO SEAMS TO MATCH either because when you sew your rows together, you offset the squares instead of matching them up, that why the edges look like binding. I'll definitely be making more of these. I think if you make them with jelly rolls, they'll end up a little bit wider and longer too!
