It is made of small 4x4 inch fiber-filled stuffed "pouches". These are then sort of whip stitched together. Teeny tiny little whip stitching. This is the only patch that has considerable wear. The other areas I will be able to stitch back together. Although, one pouch is torn, I will probably be able to sew it back together and it will have a nice little scar.
You can see how tight the stitching is. It's crazy. Like the person was reinforcing the seat of a kids' pants that tore during play. I love it. I'm thinking this is the coolest way to create a patchwork quilt. I may have to try this myself. I am wrestling with whether or not to quilt it (by hand of course) and take those yarn ties out. Ties are O.K., but I'd rather quilt it with a reiterated square about half way into each square. The maker of this quilt was, like me, a person who got to their goal with an unusual construction method. My quilting soul mate...unknown, as is.
