I like Printed Treasures--the fabric kind. The others are too thick and feel like plastic. I have sewn them to the same fabric I'm using in the quilt and sewn them on that way--like adding a border. The last time, I fused the fabric to a piece of my quilt fabric, then did a satin stitch around it. (I don't trust those edges not to peel up.) It's kind of like applique. I really liked the look of the latter and think I will do it that way from now on. The fabric is hard to needle, so adding the border of quilt fabric makes it much easier to sew them on.
