textured papers for architectural models

micro mark sells textured papers in different scales
but i amm looking for a source to download
rock/hill landscape
water/waterfall features
does anyone know of a source
i am planning to make a japanese garden
and would like some help on others experiences
previously i used "life-like"
and "woodland scenics"
but these can get expensive very quickly
and they really don't work well with paper
the other way is just printing a flat picture front and back
this is ok
but im looking for more realism
and wood models
are way too expensive
