We often hear that when it comes to making art, it’s important to experiment. While I wholeheartedly agree with this, I’ve found from personal experience that it’s much more satisfying and productive to experiment with guidance. I love to play around with different markers, pens, and paints, for example, but it’s so much more helpful to talk with someone who has already used a wider variety. Then I can get at least a general idea of how the supplies perform, if they’ll help me make the art I want to create, and if they’re worth purchasing.
On the Surface: Find the right substrate in our primer on art paper, canvas and panels
When you buy art supplies, you want to get the best value for your money. To make the smartest choices, you need to be intimately familiar with the materials you buy and use. This guide will help you make wiser decisions about the surface you draw and paint on–whether it’s paper, canvas or panels. Nothing replaces the knowledge that comes from your own experience, so it’s worthwhile to experiment with a large assortment of substrates to find out what works best for you.
Paper without a doubt is the most common and popular surface for artists to work on. Compared to the cost of what you put on the paper (charcoal, graphite, inks, pastels or paint) and the tools you use (brushes, pens or markers), paper is relatively inexpensive.
Paper is made of plant fibers, most commonly cotton or wood, but also other fibers, such as rice, straw, flax and hemp. All natural materials are subject to decay over time, which is an important consideration for the artist. Light, heat, humidity and pollutants all contribute to this process. When looking for paper that will stand the test of time, check for the words cotton rag, alpha cellulose or lignin-free.
Handmade paper is made by dipping a wooden frame with a fine screen (called a deckle) into a vat of pulp–a mixture of water and cotton, wood pulp or other fibers. After the water runs off, the sheet of pulp is removed from the screen and pressed between layers of felt to dry. The paper might then be processed further by being run through rollers. One sign of handmade paper is deckle edges, which are uneven or ragged.
Machine-made paper is produced on a Fourdrinier machine or a cylinder mold machine. In a Fourdrinier machine, a conveyor belt made of wire mesh pulls pulp through the process. The continuous sheet is dried and pressed as it passes through many rollers and is finally wound into large rolls. A cylinder mold machine works in a similar way; the resulting papers are described as mould-made.
Cheaper paper made from wood pulp is suitable for disposable work. When you’re practicing your techniques rather than producing a piece of art, the permanence of the paper isn’t a major concern, though price might be. Newsprint is an excellent choice; it’s cheap and receptive to most dry media, such as graphite, charcoal, crayons and colored pencil. It’s not suitable for wet media, however. Newsprint not only buckles when wet, it also darkens temporarily, making color and value judgment difficult. Newsprint shows signs of deterioration within a few years.
For the work you want to keep or sell, use high-quality paper made from cotton rag. If you’re using dry media such as graphite, charcoal or pastel, the paper’s texture and color will be the most important considerations. If you’re working with liquid media such as watercolor, ink or markers, the paper’s absorbency and weight will also be factors to think about.
Drawing paper made from cotton fibers is the obvious choice for dry media such as graphite and charcoal, and there are many such papers to choose from. They come in individual sheets and in pads or spiral bindings. Paper described as drawing or sketch paper is usually white and comes in a variety of surface finishes, from smooth to rough. Surface texture is also called tooth, referring to how the surface holds particles of graphite, charcoal or pastel. The softer your medium, the more tooth you want. Smooth paper is great for graphite, but it doesn’t hold charcoal or pastel as well as drawing paper with a rougher texture.
The traditional and time-honored surface for paintings is canvas. Artists have been paint- ing on stretched canvas using paints ground in linseed oil for centuries. Stretched canvas is lightweight (and therefore portable) and relatively inexpensive. Nothing compares to the feel of painting with a high-quality brush on well-stretched canvas.
Artist’s canvas is made from cotton or linen; it’s sold primed or unprimed and comes in rolls, pre-stretched or mounted on panels. Cotton canvas, sometimes called cotton duck (from doek, the Dutch word for canvas), is less expensive than linen. Linen is made from the flax plant, the same source as linseed oil. Canvas comes in rolls in a variety of widths and weights: Generally, lightweight canvas is 4 to 6 ounces, medium-weight is 7 to 9 ounces, and heavyweight is 10 to 12 ounces.
Raw, untreated canvas must not come directly in contact with oil paint, which causes the fabric to rot. Traditionally, canvas was sized with glue made from rabbit skin and primed with lead-based paint. Now artists can choose to stretch raw canvas and prime it with several coats of acrylic gesso, or use canvas prepared with an acrylic or oil primer. Stretching a canvas properly can be an exacting process but not a difficult one. The more you do it, the easier it gets. For a lucid explanation, consult Phil Metzger’s Artist’s Illustrated Encyclopedia (North Light Books, 2001). In any case, pre-stretched canvases or canvas panels provide a convenient and economical option.
Pre-stretched canvases come in a wide variety of sizes, thicknesses and textures, ranging in quality from inexpensive to the caliber for professional work of the highest permanence. As is generally true with art materials, you get what you pay for. For good quality pre-stretched canvases at an affordable price, look for 7-ounce cotton primed with acid-free gesso and back-stapled on solid wood stretcher bars. For the next step up, look for linen (preferably Belgian) double-primed and back-stapled on heavy, kiln-dried bars.
Priming Canvas: Acrylic gesso is a suitable ground for acrylic, pastel or gouache; true gesso (white pigment, mixed with a binder of glue, often with an addition of marble dust) is suitable for egg tempera and oil. If you use an oil-based ground, make sure the canvas has been sized with gelatin or glue.
An attractive alternative to using stretched canvas is painting on panels, which are made of various materials. Panels provide a rigid, stable substrate not subject to the movement that can lead to cracking on stretched canvases. Panels are made out of solid wood such as maple and birch, or out of plywood, medium- density fiberboard or acid-free hardboard. Panels come unprimed or pre-primed. You can buy panels cradled on a wooden frame for extra rigidity.
