These are beautiful! Very expensive. Great picture and description. I do not understand the comment from bettysujaya about sewing works or ironing. You cannot iron sequins. It seems very clear from your description it is an applique, which requires sewing onto another piece of fabric or garment. Great listing! Will bid for sure!
Do you think it would work to bobby pin them, or would it destroy them? I think we did that kind of thing in ballet. Also, can you tell the measurements and how large they are next to a penny? :)
