This pattern was created for using up scraps of cotton. The pattern includes 5 different charts for mixing and matching. Start working in 3 yarns and when you run out of a color, move to a 2 color chart, or just switch up colors as you run out and change charts every color change. This pattern also works well if you just want to do 1 pattern for the whole washcloth. Gauge will vary slightly per chart chosen, but will be blocked square.
