To create a cohesive collection I first start with becoming inspired with the materials. I always pick one pop of color to be the main piece to the collection. In this case the light purple hide is the main hide, while the tones of grays and browns are my accents. I often see people selecting nothing but beautiful or colorful hides to work them into a collection together. In my personal opinion, if you add to many key players into the mix, the individual one is unable to take the spot light. Through these minor mistakes of getting to crazy with color a collection can start turning from classy to chaotic.
