It's better to have two hands than one glove.
I bought the easy wrap system from Breathing Color. Oh my gosh it looks so much easier then the stretching and stapling. Thanks Guys!.

Since you bought this perhaps you'd be in the market for a set of detailed instructions for pouring **** out of a boot.
Stretching canvas prints is one of those things you just do. There's absolutely nothing to it and it's just one of those skills you need to be in this business.
After you do it once or twice you'll have no need of anyone's handy dandy stretcher system. All of those systems might be fine for someone who wants to stretch a print maybe once in their life. If you're going to be doing this sort of thing any more than that, learn how to do it with conventional stretcher bars, a staple gun, and canvas pliers. Once you know how to do it then the Little Giant Super Stretcher System or whatever it is you bought just gets in your way. It's not rocket surgery and if a doofus down to the local frame shop can do it, anyone can do it.
For extra credit, learn how to make your own stretchers out of brick mold or whatever you have laying around. That way you're not stuck with the 2" increments in which commercial stretcher bars are available.
