Improving upon one of the finest canvases in the world is not easy but Creative Mark has created a primer that actually maintains the richness and purity of the colors that you painted. Other stretched canvases have lesser quality primers and as a result your paintings loose their punch. The Edge is made with a special Tuck-N-Roll construction that provides you with four clean paintable edges for frameless presentation of your art. The Edge now features triple, acid-free all media primed 400 gram weight natural 100% cotton canvas stretched onto high quality all wood stretcher bars. Each canvas is individually shrinkwrapped and cartoned for safe storage and easy transport.
