Here are two specific painting techniques that will give you two different watercolor effects on the fabric:
1) For the all blue pillow with somewhat of an ombre effect, use highly saturated paint (with less water) at the top and keep getting it wetter and wetter as you go down.
2) For this multi-colored pillow, use circular strokes of varying colors. It may not look right until it is soaked with the wet fabric medium and dried. Then the colors all blend wonderfully.
You could also have fun with this craft using white t-shirts!
