CHOOSING THE RIGHT CANVAS FOR YOU

The blank canvas is a new landscape to explore artistic possibilities and a staple in any artists creative practice. But the term canvas is a catch-all for stretched fabric over a frame. Historically two materials have dominated the canvas industry, Cotton and Linen. Before you choose your canvas of choice, it's always good to see what’s available as there is a vast selection to be made so think about what it is you are using the canvas for, what medium you'll be using and what will help you achieve the results to suit you. In this blog we’re going to give you a breakdown of the characteristics of each to help you decide what surface is best applicable for your practice.

STRETCHED CANVAS

Canvases are generally tightly stretched on to a frame that creates a spring in the fabric when pressure is applied. The more taut the canvas ia the more enjoyable it is to paint on, as the tension in the surface has an element of vibrancy and creates a more rigid surface to paint on. The tightness of a canvas must be the same across the whole frame so that the grain of the fabric is square to the edges, with no skewing. Readymade or pre stretched canvases most commonly have a universally primed canvas stretched on to a wooden frame with bevelled edges or quandrants.

ARTISTS LINEN CANVAS

Linen is made from flax and considered to be superior to cotton due to strength and durability. It is not super absorbent by nature like cotton is and is less prone to expand and contract due to moisture. It is able to retain its natural oil content, which preserves the fibre’s long-term flexibility.

CANVAS ROLLS AND STRETCHER BARS

A lot of artists prefer to make their own canvases to their own specifications, so If you're struggling to find the right length, width or depth, in the one canvas we also have canvas rolls and stretcher bars available to meet your needs too! There are a couple of things to consider when choosing your ideal canvas and stretcher bars.

WEAVE

Canvas is measured in grams per square metre (or gsm as you'll commonly see) or ounces per square yard (oz). If the cotton or linen has a heavy weight then one or both of the following is true: it is a thick, tough yarn and/or it is tightly woven. Lightweight cotton or linens have an open weave and generally a fine yarn, they are easier to stretch and are more responsive to tightening procedures to make them more taut. The lighter weight canvases are usually used by artists who draw and/or have a much more delicate touch in their work.

WEIGHT

The heavier the weight of the canvas means the more tension the fabric can take without any tearing or ripping happening. The heavier option is best if you're aiming to do large scale paintings.

Stretching your own canvas can seem like a difficult quite time-consuming process. But the benefits are a plenty. Firstly, you give yourself a huge range of options such as meeting exact specifications: the dimensions, the shape, the type of canvas, the make and quality of the wood, and so on.

Then, having a hand in creating the surface support that you’re going to paint on allows you to take further ownership of the finished product. If you thought that finishing a successful picture was satisfying enough, there really is a lot of satisfaction you’ll get from completing that you have stretched yourself. Here's some quick tips to get you started with stretching your very own canvas.

TOOLS

2 are essentials for this is - Global Chrome Alloy Canvas Pliers are an essential for stretching canvas. Their 55mm serrated jaws grip the canvas firmly, without slipping.Their spring-loaded handle makes them comfortable to use. Also, a staple gun with staples anything from 4 – 8mm are ideal to stapling the canvas to the bars

Prep the stretcher bars and canvas

Lay out the canvas roll on a flat work surface. Place two pairs of stretcher bars on top, with the quadrant side facing down and side into each slot. Measure and compare the diagonals to ensure that you have created a correct rectangle.

Measure the edges and cut

Measure a distance of around 7cm of excess canvas away from both sides of the four corners of the stretcher bars. With a long ruler, draw lines between the pencil marks to form a rectangle around the stretcher frame.

Staple the sides

Fold one side of the canvas back over the frame. Using your stretching pliers, grip the centre of that same side of canvas and pull it tighter still. Secure with a staple in the centre of the frame. Repeat this process with the opposite side of the frame. Then, turn the frame 90 degrees and repeat the process on the remaining two sides.

Look for the diamond!

Raise the canvas and this will help you to judge whether you have the required tension. The four staples should pull the canvas nice and tight that forms a diamond shape similar to the one above. If one of the sides of the diamond doesn’t appear tight enough, remove the relevant staples, lay the canvas back down and repeat the previous step.

Tension and Finish

Its best to work your way to the corners, tightening with the canvas and stapling as you go further down. Work around the frame fro one side to the next - one staple to the near side, then the far side, then one to the corners. As you work your way to the corners with the staples, ensure that the canvas curls up in to a lip shape, similar to the one pictured above. This will ensure you can fold the corners over neatly. Hammer in the small wooden wedges or (biscuits as they are often referred to) to the slots provided on your stretcher bars.
