I agree sew on rhinestones, are the way to go. Glue gem-tac, fabric tac or a hot glue gun (low setting) drawback some fabrics don't like glue adhered and move residue from it awful.they have sticky or hot transfer ones sticky ones are only good for ipods ancell phones not a dance costume. hot transfer ones have not tried again, depends on fabric. See why i stick to sew on. Easier..
