Colored Pencil Society of America
The Colored Pencil Society of America (CPSA) was founded in 1990 as a nonprofit organization dedicated to artists over 18 years of age working with colored pencil. With about 1600 members worldwide and over 25 District Chapters in the US, CPSA provides opportunities for colored pencil artists to network. The Society is run by a Governing Board consisting of twelve artists and professionals who volunteer their service to ensure benefits to the membership and the future success of the organization. The Society provides two opportunities for colored pencil artists to exhibit their work. Both exhibitions offer cash awards and are juried to promote the highest aesthetic standards of fine art to the public. CPSA is also one the few art organizations to participate proactively in the development of a standard for their medium. With the increased use of colored pencil for creating fine art, CPSA believed it was crucial to have a standard of light fastness for this medium. Consequently, the organization has conducted ongoing test for colored pencil light fastness since 1991.
So far I really like this, much better than Das clay. It has no unpleasant odor and is very smooth, takes detail well. Has a distinct leather hard phase where you can work that way, really neat. Hasn't been long enough to really test finished strength though as that takes two weeks (it's dry though in a day or two).
