I bought a beautiful, colorful zebra picture on canvas print but it came un-stretched. I had to buy stretcher bars in order to mount the picture.
First thing I did was to dry fit to make sure fit.
Using a mallet I gently tapped the stretcher bars in place making sure the frame was square. Then I marked the back of the canvas with pencil where I wanted to place the frame.
On the back I used a staple gun to secure the print.
And here is the finished picture. I am going to hang it in my vanity area as is, gallery style without frame.
