I used the Reynolds brand wax paper that I got at the Dollar Store and only ended up using one roll, though I purchased two, to make 45 of these 18" cut sheets for my chandelier.
Take 3 sheets of the 18" wax paper at a time and place them on top of each other, then, place them in between 2 spare towels and iron until they melt together forming 1 thinker one.
Take a circle cutter, mine is the Fiskar's brand at Michael's, and if you don't have one use this 40% off coupon, set it to a 2" diameter, and start cutting circles out of the thicker, ironed together wax paper sheets to create faux capiz sells or disks.
Place the circle cutter as close to each cut out circle as you can to get the most out of each sheet. This does get tedious, but put on your favorite tunes or a TV show you enjoy and just keep going! :) I placed them into a cupcake tin as I went to keep them together and organized.
