Professional Artist Painting Backdrop Canvas - 17" Width x 40' Long - High-Quality Canvas for Studio, Photography & Theater Backgrounds

I made 12”x16” frames to make canvases for elementary students. I figured a 40’ roll should be enough to stretch 20 canvases. I just barely got through the 7th frame and the roll was gone, it had to have been less than 14’ long. I probably should have unrolled the canvas and checked the length before I started but I didn’t.It’s sad, there’s no budget for things like this so you spend your own money and make things yourself so the kids can have something extra, just to get taken advantage of by a company misrepresenting it’s products.
