The emblems, if they are attached, might be removable. If they are embroidered directly on to the cap, it would need to be cut around to remove. Then the edges would need to be finished (perhaps a satin stitch??). Either way, they are quite stiff and would not lend themselves well to a quilt. A wall hanging would be a better idea. Again, very stiff, so I wouldn't attempt quilting through the designs. Lots different than a t-shirt quilt! Good luck.
