Oh! They're adorable
I would have advised you, to make a clay sculpt and than make a mold so you can cast it in a lighter material
or make te basic shad of the horn, twist to wires togetter, to make it more volumous and wrap it around the basic shap o the horn and papermaché over it to make it smooth, but that would result in a spiral on top of the horn, not on actually in it. I like yours better
huh, that reminds me, must post pics of Olaf, the eternally unfinished puppet.
