So right now all you can make with the colored stones from the magpie is the Magpie decor, and the quartz jewelry. But I had two ideas:

Beaded Leg Wraps:
50 of each Color: Rainbow beaded leg Wraps
50 Red Quartz: Red Beaded Leg Wraps.
Etc.

They can either be the color of the stones with a beaded fringe, or made of a beadwork pattern of some sort (I cannot draw to save my life)

Beaded Shawl/Beaded Bedlah

100 quartz pebbles of a given color creates it
And like the wraps it can either have a beaded look or just a fringe
