So yeah, I finished this sample and its instructions. I'm pretty happy with the colours.
Most times I wear my original very large pendant, it garners a fair bit of attention, so I thought I'd reconsider. The truth is that the slider bead, while containing the same elements as the large pendant, requires some extra work to stabilize and finish it, while the pendant because of its structure does not. All it requires is a bit of perseverance, manoeuvring abilities with a needle in tight spaces and a little more time to complete it.
I actually think it's teachable, so I made another sample.
