It is important to have a painting space that is yours alone. It might be just a corner in any part of your house eg kitchen, storeroom, balcony etc. Whatever or wherever it is make the space yours, preferably with no interferences. It is a space where you can leave your painting in progress without the need to move or store away. If you must take out your painting materials and arrange it by the time you have set up everything, your flame of creativity may have extinguished.
