Use your favorite cardstock color - just think of the possibilities! I used CTMH Blush cardstock for the base and WorldWin Papers' Mirror-Cast Gold Metallic Foil for the smaller diamonds.
Cut/emboss eight cardstock diamonds with S4-288 Classic Diamonds #5 (remember, the smallest die template is #1, increasing in number as they get larger). Cut/emboss eight foil cardstock diamonds with die template #4, embossing with the I2-1009 Impressabilities. The above picture shows how to make your sandwich: Place your white master plate on the bottom, followed by the Impressabilities, followed by the Classic Diamonds die template (cutting side up), followed by the foil cardstock (face down), followed by the embossing mat, followed by the second white master plate. Doesn't that embossed diamond look gorgeous?
Center the foil/embossed diamond over the blush cardstock diamond, adhering with your favorite adhesive. Repeat with all eight diamonds. Score down the center as shown above, fold and crease well with your bone folder.
Use a strong glue to adhere the back of the diamonds together..
I used these cute little spiral clips to help hold the seams tightly together while the glue dried.
Before you glue the last set of diamonds together to complete the ornament, insert a long strand of ribbon with which to hang the ornament.
Here's one I made with red cardstock. I cut/embossed the smaller diamonds with white cardstock, using the same Flourishes Impressabilities. With the Impressabilities still in place, I sponged red ink through the openings in the template.
