According to Native American beliefs a dreamcatcher filters out your bad dreams and sends you only the good ones. Using this pattern learn to make a colorful mandala which can be used to create a beautiful dreamcatcher giving it your personal touch with the addition of feathers, beads, ribbons and laces of your choice. 
The pattern is also available for free in my blog
