Oil paints are extremely versatile.  They can be used thickly or extremely thinly; they can be opaque or transparent.  They are very popular because they dry slow and enable you to work with the paint for quite a while after you’ve applied it to a canvas or board.  Once the paint has dried, it can be over-painted without disturbing the original paint.
1. Always lay your oil paints out on your palette in the same order so that, with time, you’ll be able to pick up a bit of a color instinctively.

2. Avoid using Ivory Black for an under-painting or sketching as it dries much slower than other oil paints.

3. Pigments containing lead, cobalt and manganese accelerate drying.  They can be mixed with other colors to speed up drying and are ideal for under layers.

4. Use linseed oil for an under-painting or in the bottom layers of any oil painting done wet-on-dry as it dries the most thoroughly of all the oils used as mediums.

5. Avoid using linseed oil as a medium in whites and blues as it has a marked tendency to yellow, which is most notable with light colors.  Poppy oil is recommended for light colors as it has the least tendency to yellow.

6. Don’t dry your Cheap Oil Paintings in the dark.  This may cause a thin film of oil to rise to the surface, yellowing it.

7. If, as the paint on your palette dries it forms a lot of wrinkles, too much oil has been added.

If you hold your hand as still as you can, you will probably find your hand will shake and absolute stillness is something most people cannot achieve. However, if you move your hand in a sweeping gesture, you will find your hand shakes very little. By moving your hand, you can command greater control of it.

This is why it is often a good idea to paint fine detail with a moving hand, using soft, flowing gestures. Of course you can also steady your hand: either resting it against you painting, or when the paint beneath is wet, using a mahlstick or steadying your hand with your little finger.
