That is a great Idea!
can ou explain how you used them
Before I tell you how I did it I would really consider Ramblinrev's advice if I were you. He'll forget more about this stuff then I'll ever even learn lol.
Anyways if you still want to do it I just recommend checking your injector every so often during the project and cleaning up any glue buildup.
Basically all I did is make some marks along the edges of the tarp for my hems and ran the glue stick down that entire area. I found it turned out much better if I put glue on the entire edge at once instead of applying in sections. I would then start at one end and begin folding my hem to the marks I made. Now this step I would do in section because it seemed to help keep my hem from getting uneven. Once you basically get the gist of the hem in place go back and begin pinching the hem from the end you originally started at to get any air bubbles out. Also at this time the glue will still allow you to move the hem around until you get it nice and even all the way down. After that apply some more glue down the edge and fold your hem over one more time. This goes much easier and faster than the first fold. Once it's in place work on another edge while the first dries a bit and then go back and inject you some thread!
I will add that by me using the glue sticks I was able to do a nice small 1/4" hem all the way around the tarp.
