I would measure from the clasp

To separate the crystal cube beads you can use saucer shaped beads as well as daisy spacers.

You can also use rounds and daisy spacers shown here:

Crystal contains (harmless) lead. The higher percentage, the "brighter" the crystal. If you've ever seen a Waterford cut glass object and the light play it has, you'll understand the difference. Swarovski has that same light play in even the tiniest beads. Nothing wrong with glass beads, they're just different...and less expensive.

The Swarovski color Khaki and Olivine as well as Lime would work with the Mint Alabaster.  We do offer a Jewelry Color Chart which can be viewed at following the link below: http://www.artbeads.com/jewelry-color-chart.html

according to one size chart a 14mm bead is 1.75 inches so for a 7.5 bracelet it would take approximately 13 beads if you had no spacers in between them.

I would definately use a wrapped loop when using headpins that thin, not only for security since a simple loop may come open more easily but also for a more finished look.

It is Rose Water Opal.

Make sure when buying retangular toggels that the stick is not short. Many sets come with the stick too short.

Why not? I would use E6000 glue:)
