Have you ever really thought about doing this? The idea of it might be a bit awe inspiring at first, but if you don’t fly into a panic, of course, this is possible. Now, all you need is a subject for your mural.
I would recommend that before you make a start on this, that you put in some groundwork on your wall. After all, you will need a clean surface to work on. So, I would say give your wall a good wash down first, this is to make sure that you have no unwanted grime or grease on it.
Once this is dry, you can make a bit of a start by giving the wall a coating of paint or a primer. This should, in fact, make it easier to paint your mural.
Don’t get old feet now! What you will need next, is some paper, like a sheet of A3, a pen or pencil and a ruler. You now have to draw what is called a grid and you do this on the paper first. Like a plan, in fact, particularly if it is a fairly large area you want to cover. What you do, is to draw 2 inch squares to make the grid and then you draw your design on this. When this is completed you then basically transfer the grid on to your wall.
As an example, if you use 2 inch squares, one of these could represent 2 feet square on your wall. You can mark your squares on the wall by using a coloured chalk that will show up on your painted wall. Your chalk should be quite easy to erase afterwards.
I would not advise you using a small grid though, because it can be quite a problem trying to get the chalk off. You also really need to think hard about what you paint in the grid, as you will need some very definite lines to shape your picture.
So you have your paper grid, now you need some paint. What I would say is, try, if it is at all possible, not to stint on this. A good quality paint usually works better for anything. Personally, I would try to use an acrylic paint, if you can afford it. Then you paint the grid so that each square will be identical from the paper to the wall.
It is essential too, to be using a good brush. If money is an issue with the paint, use an ordinary house paint for the background part and just use acrylics for the main details.
One important fact to be taken into consideration, when you paint a mural, is that you are painting right on top of it all the time, so you need to take stock of it from a distance as you go along. It may well be that the sun will reflect on your work, so you would need to choose a paint with this in mind.
You are better to use a paint with a matt finish, as then the light will not be reflecting from this. If your work is finished, you need to be able to clean this from time to time, so do add a coat of clear varnish. This will protect your masterpiece!
