There is also a glue that you can get,,, I believe I purchased mine from a shoe repair shop it was in tubes it could even of been speed sow,, its been a while... It actually does a good job and it last as long as the canvas. A few years back we had to put in a whole new peak in an old 14x16 we had. The whole top length of the peak was in rough shape so we ran a one piece strip about 2 feet wide and the whole length and glued it in and a few patches as well.. We used that tent for a few years and that glue never let go.. We haven't used the old one much in the last 4-5 years but we do set it up once in a while for a shop for the machines and everything is still in place...
