For a more dressy set, substitute bicone crystals for the 4 mm jasper rounds. Pick a few that bring out the accents in your faux turquoise beads. Colors to consider: khaki, olivine, indicolite, blue zircon, black diamond, and aquamarine champagne.
Be sure to pick up two extra butterflies for matching earrings! Check out the PDF if you need help making these lovely lookalikes.
