Does canvas shrink when washed?
When working with the standard 10 oz canvas in natural I expect it to shrink 12-15% after it’s washed and dried. The dyed canvas shrinks a little less, usually about 8%. I think some people disagree and prefer air dry, but allowing the canvas to dry on high heat should shrink the fabric as much as it will ever shrink.
Should I wash canvas before sewing?
You absolutely should pre-wash this fabric. Cotton Linen canvas will be softened by pre-washing and will shrink quite a bit. Machine wash warm and tumble dry. This is the amount of shrinkage that occured on a 5″ square of cotton/linen canvas after washing warm and tumbled dry.
How do you get mildew out of canvas?
A mixture of 1 cup TSP, 3 quarts of water, and 1 quart of household bleach makes for a super-powered mildew killer. Just like with the bleach on its own, apply it to a moldy area, let it sit for a few moments, and then wipe it away.
