Heavyweight Art Grounds
These are the artwork supports that are heavier in weight, thicker, and usually more rigid than the lightweight grounds or foundations.
Most commonly I use:
- Cotton rugs and other papers: 300 g/m (140 lb.) and heavier;
- Canvases: heavy cotton ducks with more texture, usually with tight plied yarn weave of tighter and stronger construction, from 12 oz. per square yard (36" x 36 ") to 30 oz.
