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.
Coloring in pages that are specific for coloring. I have found a few websites that have pages to color that are downloadable. You can also try a resource store for teachers. These specific pages for coloring are pictures or drawings of a variety of design that you alone enjoy. You can make your own coloring book with these pages. After coloring the designs you can write your own narrative about how you feel. Write how the design itself and the colors you used relieved your stress. You can even write a short story about the design if you like, this is your project and it is for your eyes only.
Coloring is a great way to bond. Ask your friends over for some wine, cheese and coloring. Perhaps at first they might look at you with skeptical eyes and doubt; but hand over a fresh sheet of paper, some vibrant or glitter colored pens and in just minutes you will not be able to pry those colors out of their fingers. Soon you will be visiting easily, looking over at each-others masterpieces from time to time to admire their selection of colors. You will begin to feel like you have time-traveled back into grade 2 and you do not really want to leave. Coloring is freeing and has no expectations. The beautiful thing about this craft is that there is no pressure to finish, to use a certain color or even to stay in the lines!!! There is absolute freedom involved in those precious hours where you just get to color.
