Binders Art Supplies and Frames is my favorite place to buy supplies, specifically encaustic supplies and frames. The owner, Howard Krinsky, built the business with a determination and mission to give back as well as to be a part of the art communities where their business resides.
Binders gives a significant discount to students and art teachers. He will gladly pre-order supplies for artists to pick up if they aren't available at the store.
Check out their encaustic lines which include Encaustikos and R & F, leaders in encaustic supplies.
Look to Binders for pigment sticks and blocks, wax, gesso, brushes, scrapers, panels and cradles, hot palettes, starter kits, books and much more.
