Re: How to make your own Canvas?
Make? As in weave, shear sheep etc? Or make by buying canvas and ready-made stretcher bars.
Stretcher bars can be made by anyone familiar with woodworking, but they need to be made with high-quality wood that will not warp when many pounds per square inch of pressure is put on them.
A cheap way to go is to learn to paint on wooden panels. Often artists also glue canvas to wooden panels. You can also stretch canvas and prepare it, and then cut it free and paint on it as though it were paper. That is another cheap way to do it.
