: I did use the article and used Outdoor Fabric (great service) but had a $#@$
: of a time to get the fabric to melt right, may still buy bags for peace of
: mind. I had to rework them many times with iron. It would melt outside but
: not inside. Good luck, Don.

Don't know if it was the fabric or not, but try a lower heat with some heat proof paper (baking paper) between the iron and canvas. Gives time for the heat to get to the inside of the fabric before the outside melts. Also keep the iron moving at slow but constant rate, travelling forward then back over the seam about 4 inches at a time.
