Materials:
Small amount of main color (mc)
Small amount of contrasting color (cc) (I used ww cotton for both colors)
Crochet hook suitable for ww (I used a size I-5.5 mm)

Note: This coaster can be made thicker by making an additional circle, using rounds 1-5 then placing back sides together, crochet the final round through both thicknesses.
Note: Do not join rounds unless otherwise instructed. Place marker at end of each round.
