Artist Raft

This is my first design of an artist raft, it is a hand support designed to keep the handoff a canvas while painting fine details.
I designed this because I often smug my art due to because I cannot rest my hand on the canvas. This device works similar to an artist's bridge, except rather than going over the piece it rests on it. The device is raised above the canvas by pyramids evenly spaced under the raft. The tips point down to reduce the surface area of the canvas touched.
