This isn't specific to a particular process, but recently I've collected 
many different types of paper to experiment with. Could someone explain 
to me exactly what bristle board is? I've been playing with Strathmore 
2-ply series 400 Medium/regular surface bristle board, which looks very 
similar to Lenox 100 100% rag printmaking paper. What is the difference 
between these two? i.e. sizing, archival, etc?
Also, I'm planning a large size project and would like any 
recommendations for roll papers 42" to 60" wide. I'll have to mail order 
them because nothing of size is available in my city.
Anyone tried Arches En-tout-cas paper? 25% rag watercolor paper in 52" 
roles with Hot and Cold surfaces? Is the 25% reg a drawback?
Also, any suggestions on US mail order sources with large selections of 
papers?
Thanks for the information!
