I was browsing Tesco Marketplace and I saw this item.

Artbox 10x8 inch Value Framed Canvas

https://www.tesco.com/groceries/en-GB/p … /325325584

So I ordered two.

My thinking is that I would like to try some painting, so I ordered two with the idea in mind of having a go with one and then trying to produce something perhaps better on the other one based on my experience of having a go.

The canvases have arrived, nicely packed in a bubblewrap envelope.

With each of the canvases is a small plastic bag with eight pieces of wood in each.

Each piece of wood looks as if has been carefully produced, and is about 25 mm long, 2 to 3 mm thick and about 7 mm tall. One corner of each piece of wood has had the corner of the 25 mm by 7 mm area removed with a cut at 45 degrees to the edges.

The inner corners of the wooden frame of the canvas have slots in them.

Does anyone reading this know what the pieces of wood are for, and how to use them?

The frames are wrapped in cellophane and I have not removed that yet so as to keep the canvases clean until I want to use them.
