caitlinc, no it doesn't include directions for beaded toggles the one i made for the necklace was based on the clasp for 'rivolis in bloom' by laura mccabe. the instructions for rivolis in bloom, including the clasp, were in the august/september 2007 issue of beadwork magazine.
the loop is basically tubular peyote stitch, with 3 rows of size 15 seed beads, 3 rows of size 11, and then 4 rows of size 15s again. then you zip up the two edges of the 15s together, and it makes sort of a donut shape. i embellished with some more size 15s just to make it look a little more fancy and the bar of the clasp is just a 16x5 flat peyote swatch of size 11s zipped up to make a tube, with a couple rounds sewed on the end. hope this helps!
