Make my own pillow pet?

Pillo pets are awsome, but the two i like everyone has. So i decided to make a ferret pillow pet. I even made blueprints for it. Now i just need the materials. I need the plush in 2 colors(an off white, and black or dark dark brown). and then some chenille in off white. But they r tipically expensive fabrics. Where is the absolute cheapest place to by those fabrics? Which is weird cuz a pillow et is only 20 dollars with same materials.lol.:P but i dont want those so please dont answer saying just by a real one to save money.
