Rivolis with a new twist

These look a lot like the rivolis I have beaded before, but there is a difference. Instead of a combination of seed beads and delicas, these have three different size delicas--10s, 11s, and 15s. This means that the 15s cinch the final row of beading much neater.
The rivolis shown are 27mm Cathedral, 15mm x 20mm Heliotrope, and 18mm Sapphire.
(These rivolis are very difficult to photograph so that the "fire" in the bead shows.)
