Purchasing Canvasses Or Building Your Own?...

By Anna Meenaghan

Canvas is used, which is made of linen, a substance which is taken from the flax plants. It is very strong and I would think that much of it is derived from Ireland. You can buy rolled canvas by the metre. Some artists prefer this to set and stretch their own.

It may be that you need a certain size for your work and decide to go ahead and make your own. So for this, you will need a few basic items, which I will go on to explain. Although now there are so many ready made ones available in an assortment of shops, it is not really necessary to have to make your own.

Here listed are the materials you will need to complete the job. All important is your stretcher, basically this is four separate pieces of wood you then slot together. Acrylic gesso, a staple gun and staples, hammer, wedges, scissors, a typical fairly small household paintbrush and sufficient canvas. Make sure you only use an Acrylic gesso.

Start by slotting your four pieces of wood together to make the stretcher. Get your canvas and cover the stretcher allowing a good 2 inches overlap on the sides of it. Cut your canvas. Then, on the longest side, find the centre and start stapling the canvas to the wood. Stretch it taut across your frame. Then staple the middle the other side.

By now, I am sure, that you realize the other side has to be done exactly the same way. From then on, starting in the middle, grab the stapler and staple across one side to the other. Do exactly the same on the stretcher back.

You can staple the sides, and / or, the back, this way. It seems to be a matter of personal choice. Flatten the corners down and staple well. Now take the hammer.

You will need this to gently tap in the support wedges in the corners at the back. When this is completed you need to use the small brush to apply two coats of the acrylic gesso. You need, of course, to wait for the first coat to dry properly before you proceed to the second coat.

Textures also are important. When you buy a canvas ready made, they may have synthetics in them. They are usually made up of linen or cotton duck and are possible to buy in a selection of sizes.

Some are very tightly woven, so in turn, are ideal for painting in fine detail. With others there is quite a rough woven surface. This can be seen through your painting, which can add to the effect you are wanting to achieve.

Painting boards are good, but if they are oil based they can only really be used for oils or they will flake. Should they be primed with acrylic you can use both mediums, oils or acrylics. - 16887
