The handmade paper is an acid-free, archival “rag” paper, meaning it’s made out of cotton fibers from recycled clothing. It is a highly-functional paper and is conducive for the use of the following different media: any ink, graphite, charcoal, soft pastel, pan pastel, crayon, clear gesso (to prime the paper for heavier media like permanent markers and watercolor).
CAUTION!—The use of fountain pens and calligraphy pens is not recommended due to fibers clogging the nibs and other potentials for ink blotting and unsatisfactory results.
The watercolor paper is acid-free and archival, is made by Fluid, and is 140-lb. cold-press. It is the most versatile paper in the world, on which you can use practically any medium: any ink, watercolor, watercolor pencil, acrylic paints, graphite, charcoal, soft pastel, pan pastel, oil pastel, crayon, markers, glue, and/or gesso, fountain pens, calligraphy pens, anything and everything.
This paper also does not bleed - so in both cases you can use both sides of the paper.
