My kids LOVED this activity! We have about 10 different trees made because my kids kept going back to this HA!! And to be honest, I LOVED it also! It was definitely a family activity as we all got into it! 

They also look really nice hanging on a window as a sun catcher! And, when you are done admiring your beautiful tree for awhile you could spray it with water and watch all the colors mix!

TO DO: I just took 3 ATTACHED paper towels that have patterns already on them and drew a tree on it  Then I cut  it out and let my kids use Sharpies to dot the pattern on the paper towel! You can also use washable markers but the markers tend to bleed more!
