Now staple one edge from the middle to the one side. Remember to pull the canvas as tight as you can - an extra pair of hands is useful. Then do the same on the edge that is diagonally opposite. Continue like this until all the edges are in place. If you’re stretching a very large canvas, don’t staple all the way to the corner in one go.

You’ll get better tension by doing it in sections. At the corners, fold the edges of the canvas neatly and staple the one on top of the other. If your canvas needs a little tightening, tap in the frame keys. But don’t rely on these. If you find your tension isn’t good, rather remove the staples and start again.
