Mount Your own canvas

You'll need to know the length and width. Also, deduct a couple inches from each side and use that as your measurement when buying stretcher bars.

Sold in a variety of brick-and-mortar and online stores, stretcher bars are commonly sold in kits that you assemble yourself. 

You'll need a screwdriver, a hammer, and a staple gun or tac hammer.

If you have a stretcher bar kit that requires you to assemble it, follow the instructions from the seller.

I like to put one staple on each side before stretching and stapling any one complete side. 

The kits I buy have aligator hangers included. These are easy to hammer into the wood after the canvas has been stapled on all sides.

This is ready to hang. See post on how to create a Crinkle Painting.
