Wall letter made from cardboard,mâché, & clay polymer,

Okay; so I told my niece i would make her some letter for her wall. Of course the store didn't have the 1st letter in her name, so i attempted to make it from cardboard, paper mâché and polymer clay (to help get the flimsy parts harder). I traced a stencil in the cardboard and cut it out. The. I did the mâché, let that dry (but not completely) and then put clay in the areas that needed a little filling in. Finally I baked it in the oven, because I was tired of sitting there with the drying tool. It didn't come out that great, but once I put my embellishments, it should work!
