Marieka,
You do not need a studio or a great amount of time to create art. Whatever your medium just create miniatures. Get yourself to an art store, go online, order catalogues find something new to work with. There are even water miscable oils available. There are magazines such as American Artist, The Artists Magazine and several on special topics. They have very interesting websites and newsletters. Make an "art" project with the kids - I take a sheet of 140 watercolor paper and get 16 small pieces which are great for little hands. This is less expensive than coloring books and much more fun. Give them some water color pencils, a cup of water and watch the fun. I often carry a "kit" with the paper, pencils,sharpener, eraser, a purse size water spray bottle, and a few q-tips and a small cosmetic brush fit in a medicine bottle. I make quick sketches and the grandkids make beautiful refrigerator art. I tey to followthe advice of an intructor who recommended that we "Do Art" every day. This does not have to be an a big project, some days I just look around and compose a picture in my head or maybe jus ddodle a grey scale using dufferent techniques, imagine how to create a certain color in different media, etc. Just do something creative even if it is only setting up some fruit or a flower in a nice arraingement.
