craftgrrl | Source for scrap art paper

Does anyone know of a resource for scrap art papers? Preferably scraps that can be bought assorted in bulk. By art papers I mean any kind of hand made papers and things such as rice papers, textured papers, etc.

I'm a bit of a mixed-media artist who needs to beef up her lacking collection :(. However, I see it as a bit wasteful (physcially and in the moneysense) to buy fine art papers in the large sheets they're usually sold in. It would just be nice to have a large enough supply to be able to work freely, rather than having to keep in mind what I do and do not have on hand.

Thanks crafters! :)

*edit* Sources for scrap fabrics would be awesome too!! (not remnants, actual wee little scraps!)
