ABSTRACT:
A mushroom shaped needlepoint canvas is formed as a hollow curved shell of perforated flexible plastic material, the canvas having a generally oval head part and a tapered stem or body part. This canvas is readily modifiable by shortening the bottom of the body part, attaching limbs as arms and legs, and joining pairs of canvases to form enclosed ellipsoidal shapes atop an enclosed truncated cone base.
