If you have an archery specialty store, get a tube of fletch-rite (or fletch-tite...can't remember) arrow fletching glue. There is no need to scuff anything...just wipe it off with denatured alcohol then a CLEAN, DRY paper towel. This stuff dries SUPER fast and holds like crazy...dries so fast, in fact, that running a bead on the inside then shoving the canopy into position is nearly impossible. You can rubberband the canopy into position and run a tiny bead (the smaller the better) along the edge of the canopy where the rubberbands aren't. Move the rubberbands then run a small bead around the points that have no glue. Now run a bead around the whole edge. It's very thin and shrinks to almost nothing when it dries. A very easy and fast way to get a very clean and reliable installation. Let it cure for about 30 minutes and go fly. The canopy won't come off in the air but may be easily removed by running an xacto blade underneath it around the perimeter.

Another glue I've used with some success is acrylic based silicone. Cleans up (even cured) with denatured alcohol. Takes awhile to dry though and it always seems like I'm in a big hurry so I prefer the fletch-whatever.

rfw1953: That canopy looks very dark. Try to keep it out of the sun whenever possible or it might build up enough heat on the inside to melt it...I've seen it happen before. You probably already know this, but I just wanted to warn you in case you didn't.
