Art Alternatives Butcher Tray Palette, Medium. Bring a long-time classic back into your studio. Inter-generational watercolorists might remember the common use of butcher trays as a palette. This retro-style palette is durable, easy to clean and great as both a palette and supplies holder. Small chips on rim may be present but are purely a cosmetic blemish. The slightly bowed surface is ideal for oil, acrylic, gouache or a dry brushwork technique with watercolor.
