The process for this project is to work with your scrap strips, divided into 2 groups - color, and neutral. According to Bonnie, neutral is anything the color value of a brown paper bag or lighter. It can have print and pattern and color, as long as the background is neutral. Another factor is the value of the fabric you put the neutral next to. The darker the value of the color, the darker the neutral can be, as long as there is enough contrast.
I shared this picture before, of the blocks I got done during class.
