This is made with worsted weight yarn, less than 1 ounce of main color and scraps of accent colors. You will also need scissors and a tapestry needle to weave in ends and embroider the words. I used size G crochet hook but a similar sized hook can be used.
Row 1; Ch 16
Row 2-18: ch 1 turn, 1 sc in each sc across
fasten off main color and join accent color.
Row 19 & 20: ch 2, Puff stitch in each st across, turn
Border: sc around outer edge placing 1 sc in each st or end of each row.
To finish, embroider the words of your choice on the coaster using scrap yarn in a contrasting color.
