I continue to reflect on ways to steer sparks in a safe direction, i.e., out the garage door. One suggestion was to hang up cheap blue tarps, but I was concerned about how easily they would melt, and whether they might catch on fire.
Now I see that HF has a 9' x 16' canvas tarp on sale for a low price. Hmmm -- I would think the weave on the canvas would offer places for sparks to lodge and begin to smolder, but would there be some sort of inexpensive spray that would make it fire-retardant?
Thanks,
Andy
