Cactus spine

I'm experimenting with cactus spines at present. They really appeal to me, but I'm not sure all of you find them as attractive. Anyway, here's a shallow dof that emphasises a curved spine on one of my pricklier customers. Actually, these ones that have stout, sharp spines are easier to handle than those with fine, hair-like spines that attach to your skin, and seem to burrow in.
