Stretching your canvas
Cut your canvas with 2-2.5 inches overlap of the stretcher bars, then place a few staples in the middle of one side and stretch the opposite side. Move to the other sides and repeat. Work from the middles to the corners.
B Work your way down each side from the centre out, adding a few staples on each side, then alternating all four sides until you reach the corners. C Fold the canvas at the corners under itself, like wrapping a gift, and tack or staple in place. A Start in the centre of each side. Place one or two staples in the middle and stretch the canvas tight.
