I made this to sell at MFF, it was a first time using pretty much everything but sewing the pattern together. There's a wire in the middle to let the owner shape it, a dozen hand painted and laminated flexible scales that glow the colors that are visible in light, and three types of DF fur.

It measures 46" inches from base to tip (nearly 4 feet), so I hope whomever gets it is tall enough XD

And since it was asked: The wire inside is 2 pieces (it would be easier to fold 1 piece in half) of 12 gauge wire twisted half way up and a third added half way up and braided the rest of the way past the base and folded over to hold the tail's shape there. I hope that wasn't too wordy x.x I might make a tutorial the next time I do it since I had a hell of a time finding info on it
