I've managed to finish most of Piko's costume early this year! Let me tell you, gluing 300 feathers is much easier than sewing 200 sequins.
Inspired by MissMeander's Gold Horns Tutorial I'm making my own set of horns. Although I did not use the same kind of clay that she does. I used Crayola Model Magic for mine.
The only problem I had was that the Model Magic does not twist like a heavier material would, so it took alot of work, and many tries to get the twist in there nicely. Also, it is hard to get any kind of curved shape, or bend into the horns with this material, it sort of just droops, sags, and sticks to itself too much. So I would not recommend this material, other than for it's light weight properties, and lack of need for baking.
And in non-Halloween crafting projects, I'm finally starting on a quilt for my own bed. Modeled much after The Librarian's quilt, because I was jealous of how well that one turned out.
