It's better to have two hands than one glove.
...My question for you is....do you have a system for folding the corners...this is my biggest challenge....can't seem to do it the same way twice!
Not a system, just a way of doing it. As far as it being the same twice, it probably won't be but you sure as hell can close in on it.
Generally it goes like this...
Start stretching and stapling the canvas from the center out on each of the four sides.
When you get about half of the long sides stapled or you have only 5 or 6 inches to staple before you get to the end of the stretchers,whichever comes first, then finish stretching and stapling the short sides all the way to the end of the stretchers.
Make your corners one at a time. The important thing is to get the inside fold to start right at the top edge of the stretcher bar and not somewhere on the side of the stretcher bar. Hard to visualize but when you do a corner it should become fairly obvious what I'm talking about. Sometimes the corner of a Teflon squeegee can be used to tuck this fold right up to the top of the stretcher bar.
What you're trying to achieve is 4 hospital corners but with the piece on the outside of the corner that usually would be at a 45 degree angle coming straight down instead.
