Papertoys Wishlist

I really want to see the following turned into papertoys... TRANSFORMERS STREET FIGHTER TEKKEN and SPIDERMAN and the rest of the AVENGERS Also I'm having a hard time making new designs because apparently I'm using the wrong type of paper. What type of paper are you guys using? I've been using the A3 type of bond papers, like the ones used on essays, and they really dont do well, even. I tried various types of cardstock materials as well and they still dont work.
