How to Frame a Paint by Numbers using Stretchers?

So, you have made the commitment to a paint by numbers kit but how are you going to frame it and should you do it before or after you complete it? In this article, I will show you how to frame your painting using stretcher bars and also discuss when to do it.

Before getting started, make sure your stretchers have the same size than your canvas. If you're looking for wooden stretchers that fit 16x20in (40x50cm) canvases, you can order a set here.

When to use stretcher bars

There is a lot of discussion on the internet about using stretcher bars before or after you complete your painting. Clearly it can be advantageous to paint on a canvas that is already stretched. If you would prefer to stretch your canvas before painting it then that is perfectly okay.

However, you can complete your painting and then decide how you want to frame it. You will be considering where you are going to hang it at this point and that may affect your decision. If, at this point, you decide to use stretcher bars it will work perfectly well and is how it is shown in this article.

Note

I have not used canvas stretcher pliers in this article as not everybody has them but they can be useful in getting your canvas very tight. You can also use canvas wedges to push the corners of your stretcher bars out slightly to increase the tension in your canvas. You simply tap them in. In this case, I have simply used the stretcher bars and nothing else and the result is fantastic. You do not need to be an expert or have lots of specialist equipment.

The Stretching Process

You will need:

Step 1

Get your stretcher bars and lay them out. Check if they have a small ridge running around the edge on both sides of the frame or just one. If it is only on one side it is vital that you build your frame with this ridge on the same side on all the pieces. On this picture, you can see the ridge along the outside on both pieces as they are assembled. This ridge holds the canvas away from the frame preventing it from showing through your painting.

Step 2

Assemble your pieces of stretcher bar very carefully. They should fit together very tightly so they may be difficult to assemble. If you have any difficulties gently sand a little wood away. Be careful not to take too much off as they must fit tightly together.

Step 3

Place your canvas face down on a suitable flat surface. I used my dining table covered with a tablecloth to protect the canvas. Place your frame face down onto the canvas. CHECK that the side with the ridge is face down against the canvas. Position it exactly on the painting so that the painting will be in the correct position on the frame.

Check that your frame is ‘square’. By that I mean check that all your corners are 90°. I used a T square but you can also measure from one corner to the opposite diagonal one and repeat for the other two corners. Both measurements should be the same. Adjust your frame until it is ‘square’.

Step 4

After double-checking that you are happy with everything it is time to staple your canvas in place. Fold the canvas around the frame on one side and staple it in place. This staple should be in the center of the side you are stapling.

Stapling the canvas onto the stretchers

Add the staple just in the middle

Now repeat this process exactly opposite the first staple making sure that you pull the canvas taut as you do it. This is how you will stretch the canvas into place. Repeat for the other two sides so that you have a total of four staples in place. Now check that the frame is still square and check that the painting is in the correct place. If there are any problems you can remove a staple or indeed all four and correct it quite easily.

Staples in the center of each side

Once you are happy continue pulling the canvas taut and stapling it in place working steadily around all four sides in turn so that you work from the center of each side towards the corners. Stop approximately 2” from each corner. Check again that you are happy with your painting.

Step 6

This is the most difficult bit! Pinch a section of the corner of the canvas and pull it tight.

Pull the corner of your canvas

Place it over the frame at an angle of 45°.

Place it over the frame at angle of 45°.

Now fold the remainder of the corner over the frame so that the folded edge lines up with the corner of the frame.

Fold it over the edge

Staple it in place and staple the rest of the canvas near that corner remembering to pull it tight.

Staple the edge

Repeat the process for all four corners.

Finish all corners

Well done! You have framed your picture using stretcher bars. Now hang it in pride of place in your home and enjoy it!
