The scarf can be created from really any number of pieces of yarn. The scarf I made consists of 30 pieces of yarn - each 120 inches in length. I placed the pieces of yarn in a pleasing pattern of my liking and I placed them consistently in the same order; however, you can place the pieces of yarn in a consistent manner if you are so inclined or not - either way results in a work of art.
You will recall I selected eight different yarns. I cut a varied number of each color depending on how I wanted the scarf to look.
