When you purchase stretcher bars with a No-Frame Painting by Numbers we can stretch the canvas for you. This will create a framed picture for you to paint on at no extra cost.

Simply answer the question above the 'Add to Cart' button if you would like us to do this for you :) If you have bought more than one No-Frame design please specify what one you would like to be hand-assembled

DIY frame for our 40cm by 50cm Painting by Number kits.
Requires assembly with hammer/mallet and a right angle to ensure assembly is completed correctly.


Assembly instructions:

1/ Make sure the flat sides of the stretcher bars are all facing the same way.

2/ Join the bars at each end making sure the 40cm ends are attached to the 50cm ends.

3/ Use a hammer or mallet to secure into place.

4/ Use the right angle or set square to make sure the inside of each corner is at right angles. You may need to use the hammer or mallet to make adjustments.

  • 1/The canvas should be unpainted before attaching to the frame. We recommend you iron the unnumbered side of the canvas before you begin. Use a medium heat and spray setting on the iron. We have also found that a light spray of water on the back of the canvas helps with stretching.

    2/ Lining up the canvas with the frame and securing it in place is easier with two people. Hold the frame upright and line up the borders of the Painting by Numbers (picture facing out) with the edges of the FLAT side of the frame (The canvas is stretched across the flat sides of the stretcher bars).

    3/ Start with the 50cm stretcher bar. One of you holds the canvas across the length of the 50cm stretcher bar holding it in place at both corners. The other one pulls the excess canvas to the back of the frame and uses a thumb tack halfway along the stretcher bar to secure it in place.

    4/ Turn the frame upside down and align the second long edge of the canvas across the length of the 50cm stretcher bar. Pull as tightly as you can and once again secure the canvas on the reverse side with a thumb tack halfway along the stretcher bar.

    5/ Lie the canvas down and check that the sides are stretched enough and that the borders of the Painting by Numbers are as close to the frame edges as possible.

    6/ Flip the canvas to the back of the frame. One of you pulls the 40cm canvas length to the back of the 40cm stretcher bar and holds firmly. The other one pushes in a thumb tack halfway along the stretcher bar to secure it in place.

    7/ Repeat for the final 40cm stretcher bar. You should have 4 thumb tacks in place – each one halfway along each stretcher bar.

    8/ Look at the Painting by Numbers side. Check that the borders of the design line up as closely as possible to the edges of the frame on all 4 sides. You may need to remove a thumb tack and pull the canvas more. We have found that it is not always possible to have the borders aligned exactly to the frame. You can paint these areas with the nearest adjacent number/colour, or paint in a border.

    9/ Finish securing the canvas along the back of each stretcher bar using thumb tacks across each length. One of you pulls the canvas and the other one attaches the thumb tacks. The canvas should be tightly stretched across the frame.

    10/ Finally fold in each corner and secure in place with thumb tacks. If the canvas is too long you can trim it back with scissors.

    Finally, hammer in place any protruding thumb tacks.
