Paper Casting

I've been researching casting with paper and alternative materials.
I found a really great book, Paper, Metal & Stitch by Maggie Grey and Jane Wild.
It covers paper making techniques, incorporating paper, metal shim and fibers into art pieces.
A lot of the designs can be made to include ephemera and found objects as well as printing designs on metal and fabric. The book also describes texturing for paper designs, such as embossing and additives. Mold making techniques discussed include polymer, softsculpt or formafoam , collagraphs and latex rubber methods.
I think these ideas will work well with the designs I have thus far and the book was very informative if you've never worked in paper craft before.
