• STANDARD CRESCENT WATERCOLOR BOARDS feature a 100% rag, acid-free, 140lb watercolor sheet mounted to triple-thick board. A very well known product, it elminates the need for restretching. The only drawback is the board it is mounted to is not acid-free.

• PREMIUM CRESCENT WATERCOLOR BOARDS feature the same high quality 140lb watercolor paper but this time the paper is mounted to 100% acid-free, archival white core board. This is a lovely item and very professional. The paper is heavily sized so colors sit on the surface well and the sheet will take constant reworking.
