There are various schools of thought about cotton vs. poly-cotton canvas in canvas sewing work. We have come to prefer 12oz (407g/m2), FWR polycotton for our tent covers and for most canvas sewing, as it has a higher tensile strength and is more rot-resistant than the equivalent in cotton. You probably couldn’t tell the difference to look at, but you could in how long it would last.
We have lighter and heavier fabrics available e.g. we sometimes work with 18oz cotton, for a heavier, more rugged feel, especially for some of the smaller canvas products like Bushcraft Gear, and for old type tents.
Synthetic fabrics such as acrylic are another option, which are more expensive, but greatly outlive all other possibilities.
This is a complex subject, but obviously one which is essential to get right. Canvas is usually WR (water and rot-proofed), or FWR (F for flame). There have, over the years, been many proofing scare moments, so we went to the UK’s only canvas proofers and worked with them to manufacture a canvas better suited to the British climate, which involved upping the water head (the level of water proofing agent). This canvas is now becoming the norm with some other yurt-makers too, we are glad know we have contributed to having longer lasting covers for everyone. This canvas proofing is our standard one now, and the trade mark of all our canvas sewing work.
A word of advice: don’t bother with cheap canvas.
We recommend reproofing your canvas every year (and not leaving it unattended in winter), as this can double the life of your canvas, and can point you to the best paint-on reproofing solutions.
