I was picking out some coloring books for my friends children when she informed me that she would like to get a couple of books too. This is a 30 something year old woman. She then began picking out colored pencils as well with a gleam in her eye like a kid in a candy store. She couldnt wait to get home and start coloring in her new books. She picked Barbie Doll, princess type books and methodically chose what colors she would use for the first picture.
When I was a child I just loved to draw and paint but, as I remember, before I even could begin to draw accurately I used to color in. The next stage was to learn to draw using stencils and then I graduated to be able to draw freehand which provided me with an absolutely fantastic sense of achievement. I went on to love drawing but the point I am trying to make is that it all started with the simple yet effective art of coloring in!
You can metaphorically take a page out of a coloring book, and break up the work into a few sections. Each team member or group within the team should first be instructed on which part of the page they are going to color, let them know what color they can use, and when their turn will come up. Next, after each team member has finished their part of the coloring than take the completed picture and hangs it up so that every one can see their part of the picture and the entire teams contribution.
