This is square #20 of the Knitter Knotter 2022 Mystery TCAL. Complete information on the TCAL is available in the facebook group: Knitter Knotter Hangout or at http://www.knitterknotter.com.

The sample was made using LionBrand Heartland (worsted weight) but any worsted weight yarn will do. In general mosaic patterns show best with contrasting colors. It is possible to use a color change yarn with a contrasting solid, but for this square, I don’t recommend it.
