Draw Tattoo Flash

A skill that many seem to ponder is how do to draw a flash tattoo. Now you can learn it with this guide.

Steps

First, choose a design. Pick something that reflects your personality or interests that you can easily draw, unless you want to invest some time into this step or have an eye for detail. For example, you may choose a flower, star, or a pair of lips. Perhaps if you are a diver, you may add a fish, etc.
Make a sketch of what you want your tattoo to look like. This does not have to be perfect, as you can always add details later.
Add details to your sketch and smooth out any edges, etc.
Carefully outline the drawing, but make sure as to not press or outline too hard, as this will make mistakes almost impossible to erase.
Lightly color in the drawing. Try to color everything with even pressure as to not make it choppy or uneven.
Shade in your color drawing, by darkening the areas where shadows (generally the right side, and top or bottom, depending on your perspective)would be with a pencil or a slightly darker shade of the color you are using. (This step may not be needed for more simple designs)
That's it! If you want black and white flash then do it with pencil and black color pencil, or try doing it with a marker.

You could bring your flash to a tattoo parlor and they'll tattoo it on for you but they'll probably change it around a little unless you tell them not to.
If you like your flash frame it and hang it up.
