A stretched canvas the size of the painting you would like to do. It’s a good thing to also purchase several small “canvas boards” for practice and preliminary studies. You can also use canvas paper or canvas that comes in pads, as long as they say they’re suited for oil painting and are gessoed. Try to choose a small board with the exact proportions of the stretched canvas but if it’s not, get one larger so that you can mark up that shape on it. Tubes of oil paint in a basic palette. If you’re purchasing a set, it probably has all the most essential colors. The smallest essential palette has red, blue, yellow, Burnt Sienna and a large tube of white. If it’s Winsor and Newton open stock, get Lemon Yellow, Permanent Rose and Ultramarine or French Ultramarine (they are chemically close. ) If it’s choosing primaries out of a set with more colors, use Alizarin Crimson or whichever the more purple cast red is, not the orange red. You could do without the Burnt Sienna but there’s a reason for it besides mixing. If your set doesn’t have it, use the reddish brown. Buy the oil and thinner. Linseed oil is a traditional oil painter’s medium. Some artists like walnut oil better. If you want your painting to dry faster, choosing a medium like Winsor & Newton’s “Liquin” will make the oil painting dry faster. You will also need turpentine, or odorless turpentine substitute, sometimes called turpenoid, or white mineral spirits. This is a thin liquid that has a strong or slight odor, it’s a paint thinner as opposed to a medium. Odorless paint thinners, like Weber’s Turpenoid or Gamsol, are reputedly healthier to use, but always have proper ventilation when using volatiles. Oil paint itself is not toxic in the way that turpentine is in that it doesn’t give off toxic fumes. But some oil paints contain toxic ingredients like cadmium and cobalt that can be quite harmful if ingested. Never eat, drink or smoke while using oil paint. Buy some removable artist grade varnish such as Damar varnish intended for oil paintings. Varnish will probably have some toxic fumes and should be applied outdoors or in a well ventilated area. Definitely choose a removable artist grade varnish. Varnish is supposed to be added after the oil painting has completely dried all the way through and chemically changed to “cure. " At that point a clear removable varnish gets added to give it a nice glossy finish and protect the paint layer. Every 25 to 30 years, the varnish should be removed by a conservator (or the artist or owner) with a varnish remover solution and reapplied, because the varnishes become yellow over time and aren’t intended to be permanent. This is why very old oil paintings turn brown. They often just need cleaning and a clear new coat of varnish to look as bright as if they were painted last year. You don’t need to buy the varnish before finishing the painting, since you won’t use it till the painting’s done and completely dried. “Retouch varnish” can be used as soon as a painting is touch dry. It doesn’t hurt the paint layer, but the painting should feel thoroughly dry and you should wait a good month before using it. That gives a temporary finish if you want to sell the painting sooner. Buy the brushes. Stiff ones are preferred. Bristle brushes are less expensive at the cheap end but good ones of either white synthetic fiber that’s as stiff as bristle brushes are just as good. Some oil painters also use a soft sable brush with a long handle for different effects. Get a range of sizes, large medium and small, for blocking in areas, painting in the forms and objects and quite small ones for final details if you like detailed realism. A soft “rigger” brush with very long thin soft hairs gets used for ship’s rigging, cat’s whiskers and other long linear details in realism, it holds a lot of very thin paint and can be used to write your name small or do long smooth lines. For a beginner, it’s recommended that you try a variety pack of bristle or synthetic bristle brushes with different shapes and sizes to discover the style each one creates. Palette knife, painting knife or non serrated butter knife to serve as one for mixing paint. Palette knives are pretty cheap though if you get the plastic ones. The nicer metal ones don’t stain and will last for years if kept clean. Painting knives have different shapes like trowels and angled things, each has a different effect and you can use those instead of brushes to do your whole painting. Charcoal or a violet pastel pencil to sketch on the canvas. A palette to put your oil paints on while using them. This can be an actual palette with a thumb hole or you can improvise with a cheap plain ceramic, glass or melamine plate. Something that could stand up to being washed off with turpentine is good. Many artists prefer a gray palette because the colors show up truest on gray. If you use a flat piece of glass on a table (very cheap if you take it out of a cheap photo frame) you can put gray paper under it to have a gray easily cleaned palette for every time you need it. Two small cups for oil (or Liquin) and thinner. Some sets come with a “double dipper” that clips onto a palette, if so then your set probably also has a palette. Painting rags. These can be any kind of clean rags. Strong paper towels will work but cloth rags are reusable if washed. Cloth baby diapers that have been used and washed, even worn out stained ones, make really good painting rags. Paper towels wear out fast––it’s better to use old clothes that are soft like old t-shirts and stuff like that, actual rags. Try not to use fuzzy ones that shed though, since you may be wiping out painted areas with the rags. Use rags that are about at the end of their usefulness, unless you want to wash them out and keep reusing stained ones over and over. An easel to work at, either a table easel set up on a table or a standing easel. This doesn’t need to be expensive. The cheapest “display easel” will hold up any reasonably sized canvas at a comfortable working angle and its legs will adjust to a standing or sitting height. Unless you’re disabled by age, disease or injury limiting the amount of time you can stay on your feet, it’s much healthier to stand at the easel. This will also let you stand back every few strokes to see how the painting looks before adding to it, which makes for a better painting. You can also prop up the painting against a chair or other support, or otherwise improvise something. A “painting horse” is a bench with a board sticking up at the end that you straddle and prop the canvas into a groove. Sketching supplies to plan the painting - pencil or charcoal, sketchbook or drawing paper or even scrap paper. They don’t need to be archival since these are working sketches but if you like your sketches, you might as well get an actual sketchbook and use a soft pencil or even a pen or marker for it. Just something to sketch with and something to sketch on, your favorites. Your usual sketchbook and favorite drawing tools. A safe, dust free place to put the wet painting to dry where nothing is going to bang into the wet side to smear it. Drying times for oil paintings vary from a few days to several months. Some types of oil painting take up to a year to “cure” before they can be varnished. That said, you can let it dry for a day or two before painting new layers.
In the sketch, make sure the light falling on the person, objects or landscape elements is all going in the same direction. Pay attention to where the shadows go. They should all go the same direction and are shorter when the sun or lamp is high, longer if it’s later or earlier in the day and the sun is low (or lamp is low). Directional lighting will make all the objects look more three dimensional. Draw the shapes of the shadows carefully and most of your subjects will look three dimensional at that point. This makes for good Impressionism or realism. If you want to do an abstract, do the pencil sketch loosely and work out where you want particular effects like spattering or strong texture strokes. Or skip the sketch stage on paper and proceed to the next. Sketch the subject on the canvas board, canvas paper or canvas pad. Use charcoal or your violet pastel pencil. Mark up the exact proportions of the canvas on the board or pad if it’s not exactly the same shape, so everything’s placed the way it is in the planning sketches. Do this drawing as pure outlines. You can get detailed for realism by marking up eyes, mouth, any important shapes on it or you can keep it very simple just to the main shapes and main shadow shapes. Either way it should look like a Paint By Numbers canvas when the sketch is done. If you make mistakes, wipe off the charcoal or pastel pencil with a damp cloth, let that area dry and draw it again. Very correctable.
Wow. The transparent value painting in Burnt Sienna usually looks pretty cool at this stage. It’s still easy to change if you got it too dark somewhere or too light somewhere. Take a rag and wipe off the part you don’t like and redo it the right value, or add a little more color. Or wipe out and change the shape. Gee, you thought oil painting had to be perfect, nope, it’s very easy to correct and make changes all the way through. This stage will dry pretty fast, within a few minutes to half an hour. The thinnest parts may be touch dry by the time you finish the other corner. It only needs to be touch dry.
Worst case, a painting that has Lean over Fat can slide off the canvas on a hot day, losing all paint cohesion. This happened at least once to a past student of a teacher who told the story. Never use oil pastels under oil paint because their oil formula includes mineral oil that never dries. You can optionally add oil pastel marks on the last layer of an oil painting when it’s touch dry.
Unless you want a really ugly special effect, like painting a zombie’s face and putting a big pocket of fat in on the cheek, then letting it dry wrong, then ripping it open to have the paint skin dangle down and the clump of brownish-red fat paint hit the air and dry solid, maybe dripping over the rip. Almost any mistake can be turned into a special effect once you know how it works.
You can help to speed up the drying process for oils a little by storing the painting in a warm, well-ventilated and well-lit room.
You can try this method if you have a lot of time to let each glazed layer dry before doing the next. But if you don’t want to take that long, just let the grisaille dry, add a bit of oil, paint over it in the right colors and add one final glaze when that layer’s dry. You can get as elaborate or as simple as you like with oil painting.
