They are made by Canson and is the Montval All-Media Book. The pages are 9x12 and the paper is acid free, 90 lb. cold press watercolor paper. If I don't collage paper onto the pages first, I add gesso to the pages before I start working on them. I also add water and drops of ink when I work with spray inks. The paper does take wet media quite nicely!
Once I am finished with both sides of the pages, I add them back onto the coils, which is pretty easy. I like working with a flat page and these journals have become my favorites!
