I thought I was ready to bond the canopy to the frame but decided I didn't like the lower edge of the canopy I trimmed awhile back. It was a little long and not that straight. So I marked a new line along the bottom of the frame with a black Sharpie. Then I placed the canopy on a pair of stands, covered it with a blanket and warmed it up a bit with a small heater. I used the Van's cutting wheel and trimmed to the new line. I sanded the edges smooth and spent an hour or so cleaning up the mess I made.
