Low Profile Canvas Stand

My girlfriend makes and sells art. Her stands for her pieces took up more room than the canvases themselves, so I just drew these up for her, while trying to use as little material as possible.

I tend to duplicate it, and mirror one of them, so both ends can have the flat side out.

The laptop in the picture's not exactly a perfect fit, but it's a heck of a lot heavier than a canvas, so I figure it makes for a good demonstration.
