I also use the canvas DD ones - mine are 2 layer 16oz canvas, not sure all are double layer.
I have given the fronts a spray with a clear acrylic laquer to seal the threads so cobblers pegs,bindies & other seeds dont stick to them, not that they really stick to the canvas material anyway, but the hem can get full of them... but not anymore.
I detect on a number of properties and the owners woud be seriously upset if I was spreading weed seed so I try & do the right thing.
Also makes dust & mud wash off them much easier & I suspect helps the snakeproofing.
