It is believed that the Ojibwe/Chippewa tribe was the first tribe to make and use Dreamcatchers, which were then adopted by other tribes.
The women of the tribe wove the magical webs by using willow hoops and sinew. These "webs" were believed to catch the bad dreams and allow only the good dreams of positivity and lightness to filter through.
Most believe the best colors to choose for a Dreamcatcher are white and blue, symbolic of hope and pureness. White also represents freshness, goodness, simplicity and coolness
