I am sure there are many different ways to do it. I prefer to take mine all apart and remove all the plastic parts. I arrange the layers like I want them and then I clip a salon clip on one side to hold them in place and I stitch around the center hole of the flower (usually about 8 stitches). I then cut out a felt circle for the back, glue on the rhinestone/button center and glue an alligator clip to the center of the felt circle! This works best for me!
