These painting canvases are made from 1-1/2" by 3/4" or 2-1/2" by 3/4" select pine lumber. I used pocket holes to fasten the corners and then reinforced the corners with metal L-brackets for canvases smaller than 36" and with 1/4" or 1/2" plywood triangles to reinforce corners on frames larger than 36". Once the frames are made, canvas can be stretched over them and fastened with staples on the back side.
This is also a great way to create acoustical panels to help muffle sound in a room - or for those at home Zoom calls!
The lengths of the boards are up to you to decide the size of your canvas. Check out the tips below in the steps section for how to reinforce smaller or larger frames.

1-1/2" select pine lumber with 2 pocket holes at each end.
Metal L-brackets to reinforce the corners.

Canvases larger than 36"
2-1/2" select pine lumber with 2 pocket holes at each end.
8"-10" plywood triangles 1/4" or 1/2" thick to reinforce the corners.
Screw triangles to the back side of the pine frame.
A perimeter frame of 1-1/2" by 3/4" select pine makes the frame stronger and gives it a thinner and more premium edge for stretching the canvas.
