From the book:
“Once you have mastered the spiral, you may not yet feel confident enough to begin working in a single color. This bracelet allows you to keep track of your work in a different way. In a spiral you are always putting color A on top of color A, B on top of B, etc. Here you will work four beads of color A in a single round, so in the following round you will be working color B on top of color A four times. You can keep track of the beads in each round by counting four beads of a single color. If you crochet a B on top of a B, you know that you’ve decreased a stitch.”
