Yes, the base is sometimes a thick wire with the thin wire wrapped around it but when I tried to do it (twice) with the roses, leaves and beads it was very difficult and was not neat as that one is. It came out really messy.
I've since given up on the idea of the beads standing away from the necklace and finished one today just using the flowers and the beads individually attached to a chain. It isn't my original plan but it's passable. I'll probably keep this one for myself and try to make better ones to sell.
One thing I did learn from this experience is that my leaves were only textured on one side and after the necklace is made they tend to flop around and several of the leaves show the untextured side. That would be too annoying for a customer to have to constantly make sure the textured side was facing up, so I have to either texture both sides of the leaves or make a leaf cane. I eliminated the leaves altogether in the necklace I finished today.
When I get it photographed I'll post it.
Thanks for all your help.
