This 3-dimensional stretched canvas features a 7oz (200gsm uncoated), medium texture, acid free cotton duck canvas making it the perfect choice for a wide range of painting mediums and styles. The canvas is sized and then triple primed with a universal acrylic titanium primer giving it a final weight of 13.5oz (380gsm), before being wrapped around and back stapled to quality wooden stretcher bars that have been designed with a tapered lip to prevent painted canvas "halos". This allows painting to continue from the surface onto all 4 staple-free side edges, thus creating the 3D effect that does not require framing. Each canvas is supplied with 8 plastic canvas tightening wedges and is individually shrink wrapped for protection.
