They kinda look like they are stiffined somehow to make the loops stay perky. maybe the inside of the fabric has that iron on stuff that makes fabric stick to other fabrics when ironed on. ( does that make sence, cause i forgot whats its called )
then the edges are jusr folded and ironed down then shaped into the bow. I dunno, i could be completly wrong but the second set kinda looked like they might be made that way!
