Thank you! How small do you typically make your miniatures(In square centimeters)? If they are over two square centimeters you could get some thin eye pins and cut them to length. I have some real thin ones I could post the measure ments of them a picture of one if you'd like.
Take ANY soft cable and split the braid of tiny copper wires. To change color to darker heat the wire over the stove. There are also ways to make copper green with household chemicals. I hope that helps ;]
How cute~! It would be interesting to find something to re-create the spikes/spines on the cactus, though I can't think of anything that would survive the oven unless you glued little individual strands of fur on there after it'd been baked. That would be some crazy delicate work though l3
