How to Clamp a Frame Backing for a Painting
Making your own picture frames will save you lots of money on framing, and will give you the freedom to customize size and molding. You can make your own frames using picture frame molding, builder's molding or lumber to create your own unique style. Once you have chosen and cut your wood, you must glue the pieces together and clamp them to prevent shifting and to ensure good adhesion. Clamping the frame is of utmost importance and must be done properly to ensure that your frame is straight and strong.

1
Measure the canvas and cut the lumber or molding to size. Cut each of the corners at a 45-degree angle. Use sandpaper to smooth the cuts so the surfaces fit flush against each other. Smear both sides with wood glue.

2
Loosen the screws on the wood clamps until the jaws are open wide enough to fit over the corner of the frame. Place a wooden shim on the side of each corner joint. This will prevent the clamps from leaving marks on the wood.

Slowly tighten the screws until the corner of the frame is tightly clamped between the jaws. Repeat for the other three corners. Wipe off excess glue. Leave the frame clamped until the glue has cured.

Tips & Warnings
Stain or paint the wood before you cut it to size.
A miter saw will give you greater accuracy than cutting by hand.
Once the clamps have been removed, use tiny framing nails or staples to give the frame greater stability.
Do not over-tighten the clamps or you will damage the frame.
