The rivoli's that I find seem to be expensive does anyone know if the is a cheaper alternative?
It would be helpful if you would say where you have been looking and the prices you feel are too much. Hard to make a comparison for you.
Etsy.com/shop/buttonsandshanks 100's of buttons
Have you checked out fusionbeads.com? I feel that they have really great prices for their Rivoli's. Keep in mind also that Its Swarovski Crystal so your gonna be able to get a good deal but nothing to cheap. if its too cheap I would question the valididty of it being a REAL swarovski.
Hope this helps!
