Working with paint, colored pencils, chalks or other mediums give the artist in us the freedom to try new color combinations, different compositions or designs for future patterns. Other benefits are the ability to try different styles of art and learn design terms and implement them into study sketches.
Google "free online art classes" and a variety of options are listed. A great option is to try several of the free classes and find a style or class that inspires you. Expanding on that training can be done with a local teacher in your area to get more indepth instruction. Online paid classes are another great option. Artist Network TV is a good place to start as a variety of paid classes are available.
The Virtual Instructor has some free classes to understand the basic elements of design and color theory.
Jerry's ArtArama has a vast library of free videos to choose from. Choose by medium, teacher or even product demos to find hours of free instruction.
In addition to the standard categories Arty Factory has a category of Art Movements if you would like to study about Impressionism, Post Impressionism, Expressionism, Cubism, and Pop Art just to name a few.
There are many more options for online instruction. I have listed just a few to give a jumping off place for inspiration and to show just a small portion of what is available.
If you have found your art going a little stale or have developed an artistic block, a free online course might be just the kick start you are looking for. Jumping into something new will get your thought processes freed up and inspiration flowing again.
Have you taken a free or paid online course? What did you like most or least about it? I would love to hear your thoughts.
