This pattern was used for the MCAL for Mystery 220 (more or less) group, in October 2023.

Here is a chance to use up some random colored scraps of cotton yarn!

You will need 4 contrasting colors of cotton sport weight yarn. You may use as few as 2 colors or as many as 5. My directions are for 4 colors, but if you a different number, it will be clear what to do.
The total yardage will be approximately 30 yards for each coaster. The first color will use the least and last color the most.
