staple all along one long lenght of the frame, then do the opposite side, pulling it very tight. Next do the short lenths, one at a time.
did any of that make sense :o) you get what you get here folks.
when you get to the corners fold them in kind of like you are wrapping a present and staple
i'll have to admit i really did feel kind of cool using this staple gun.
*cost of this project:
not too shabby! and so much fun!
