Loxley Canvas Stretcher Bars
Many artists appreciate the benefit of being able to stretch their own canvas to their own tastes. Here you will find quality wooden stretcher bars, available in 17 different sizes, all 18mm deep. The bars come in pairs, with 4 wedges included with each pair.
To make a frame you need to buy two pairs of stretcher bars (priced below per pair). For example, to make a frame 18" x 24" you would need to buy one pair of 18" stretcher bars and one pair of 24".
Generally speaking you need to buy a frame that is 2" smaller than the canvas (in both length and width) to allow for overlap on the sides, so the canvas size to fit an 18" x 24" frame should be approx. 20" x 26".
Similarly to buy a frame for a canvas 24" x 36", you would need one pair of 22" and one pair of 34" stretchers, and you will end up with a frame that is 22" x 34".
