Canvas is lightweight making it easier to hang multiples. The canvas wraps around the sides and has a fancier back, making it perfect for tabletops. Fabric is sealed with a high quality gesso so you can safely staple or penetrate the canvas without fraying threads. The triple primed white is ready for paint, and the connectors can also be painted. Acid-free and pH balanced. Includes 2 each of canvas, top hooks, nails and canvas connector clips.
