The one named Cottage1 is an example of a cab with a thick flat edge. You need to use large beads (#6 here) for the base row to sit above the edge of the stone – so that your bezel row of smaller beads can nestle on the stone and base row, thus holding the stone.
Plume_agate2 shows a stone with a fairly high dome, but it slopes nicely down to a thin/sharp edge. This allows you to use size 11 beads for the base row around the outer edge of the stone, and size 15 beads for the bezel row. There are many more color choices in the smaller size 11 & 15 seed beads, so it’s much easier to match bead color and stone color.
Barbara also included a couple photos of my wire wrapping. Do you see the stork sitting on the bank on a misty morning?
The cottage stone was cut and polished by Barbara's late father.Barbara said "I’m not positive what type of agate it is, but I immediately saw a thatched roof ‘cottage’ reflecting into a pond, with small fires or colorful flowers on the bank. Finding 2mm peach aventurine beads for the twisted row was a challenge, let me tell you, but I think Dad would have liked what I have done with his stone."
Thanks for sharing Barbara, and thank you for your purchases!
