Working entirely in durable cotton yarn means these coasters handle warm mugs effortlessly and go straight into the washing machine when holiday spills happen.

Working in continuous rounds without joining.

Rnd 1: Magic ring, work 6 sc in ring (6 sc).
Rnd 2: Work 2 sc in each st around (12 sc). Sl st to the first st to join. Fasten off Cream, leaving an 8-inch tail for sewing.

Assembly

1. Position the flat Cream pompom at the very top tip of the Crimson Red hat. Use the yarn tail to securely sew it flat against the point.
2. Weave in all loose yarn ends securely on the wrong side of the coaster using your yarn needle.

Finishing

Block your finished coaster lightly with steam or by pinning it flat on a blocking mat and spraying with water. This ensures crisp edges on your hat and smooth scallops along the brim.

Size Customization Tips

• Making it larger: To fit oversized mugs, add 2 more increase rows to the hat body (increasing by 2 sts per row), and adjust your Cream brim foundation row to match the new stitch count. Add one more shell repeat for every 4 extra stitches.
• Making it smaller: Stop the hat body increases a few rows earlier for a petite espresso mug coaster.

Care Instructions

Machine wash gentle in cold water with similar colors. Lay flat to dry to maintain shape. Do not bleach or iron directly on synthetic labels.

FAQ

Can I use acrylic yarn instead of cotton?

While you can use acrylic yarn, 100% cotton is strongly recommended because it absorbs moisture from cold drinks and handles heat from hot coffee or tea without melting or degrading.

How do I keep the pompom from wobbling under my mug?

The pompom in this pattern is crocheted as a flat little circle rather than a fluffy 3D sphere. This clever design gives you the look of a Santa hat pompom while keeping your tabletop and mug completely level.

Are these coasters beginner-friendly?

Yes! The hat is worked in simple single crochet rows with straightforward edge increases, and the brim uses basic double crochet shell stitches that take just minutes to master.
