Cut two sections of beading chain, one at about 9" and the other at about 11".
Attach a crimp end to one side of each chain section.
On the shorter chain, string an alternating pattern of 5 briolette beads, and 4 bicone beads.
On the longer chain, string a bicone, briolette, and bicone. Add the crystal setting, using the two holes that are located across from each other at the end with one prong. Add 3 more crystal beads. The bicone shape will nestle into the edelweiss setting.
Attach a second crimp end to the opposite end of each section of beading chain. (Hold the chain up to make sure you attach the ends facing the same direction.)
Set the edelweiss stone into the setting.
Create 2 sections of rollo chain, each approximately 4" long. This chain isn't soldered, so you can open a link to separate it.
Using a medium sized jump ring from the assortment, attach the two beading chain sections to one rollo chain section. Attach half the clasp directly to the last link at the other end of the chain. Repeat for other side.
This finished necklace is about 19". You can make it longer or shorter by changing the length of the beading or the rollo chain.
