I used cotton duck for painting for years before I started using linen. I think 7oz much too light - I would guess "sailcloth" at 16oz (possibly 12oz) would be ideal. The other important thing is to make sure the cotton is woven with the same number of yarns for warp and weft (both directions). I'd suggest simple "cloth" (one yarn to one yarn each way) - no twill as this sometimes comes in lower weights (7oz, 10oz, 12oz, etc...). I would seek unbleached which has a natural color. New York Central Art Supply in NYC might have this online. Also Peal Paint in NYC. Most places will have a sample swatch booklet for free or a a small fee.
