A pile of white cotton yarn creates this whimsical coaster that resembles a snowman who has lost his shape. The piece feels dense and absorbent, providing a reliable buffer between a hot coffee mug and your wooden coffee table. This project suits beginners who want to practice increasing in rounds, as well as gift makers searching for small items to stuff into holiday stockings. Making these brings a sense of accomplishment because they work up quickly while remaining sturdy enough for daily use. You will learn how to maintain a flat, circular surface using basic single crochet stitches throughout the construction process.

Why You’ll Love This Pattern

This beginner-friendly crochet coaster pattern uses simple single crochet stitches and a tight tension to create a sturdy, heat-resistant surface for your mugs. It works up in under thirty minutes, making it an ideal choice for using up small amounts of leftover cotton yarn from larger projects. Because it relies on basic increases, you can easily memorize the pattern repeat after just one coaster, allowing you to build a full set while listening to an audiobook or watching a show. The circular construction prevents curling, ensuring your coasters lie flat on a tabletop every time.

I managed to whip up a matching set of four in a single afternoon. The instructions are incredibly easy to follow and the final shape is perfectly round without any awkward bulging.

Pattern Overview & Skill Level

Skill Level: Beginner
Approximate Time: 20-30 minutes per coaster
Construction: Worked in continuous rounds using a magic ring to ensure a tight, hole-free center.
Finished Dimensions: Approximately 4 inches in diameter depending on yarn choice and individual tension.

Materials & Supplies Needed

Yarn: Worsted weight (#4) 100% cotton yarn, approximately 15-20 yards per coaster. Cotton is preferred for its heat resistance and ability to absorb moisture.
Hook Size: 4.5 mm (US 7) to create a dense, functional fabric that prevents liquid from seeping through to your furniture.
Notions: Tapestry needle for weaving in ends and a stitch marker to keep track of the start of each round.
Safe Yarn Substitutions: You can use acrylic yarn, though it is not recommended for hot drinks as it can melt or deform. Wool can be used but may felt if washed in hot water. Using a heavier yarn will result in a larger coaster, while a lighter weight yarn will require an extra round or two to maintain the same diameter.

Stitch Guide & Abbreviations (US Terms)

MR: Magic Ring. A method of starting a project by crocheting into an adjustable loop.
ch: Chain stitch.
sc: Single crochet. Insert hook into stitch, yarn over, pull up a loop, yarn over, pull through two loops on hook.
inc: Increase. Work 2 single crochet stitches into the same stitch to add volume.
sl st: Slip stitch. Insert hook into stitch, yarn over, pull through both the stitch and the loop on the hook.
st/sts: Stitch or stitches.

Step-by-Step Pattern Instructions

Coaster Body

Rnd 1: Start with a MR. Work 6 sc into the ring. Pull the tail tight to close the center. (6 sts)
Rnd 2: Work 2 sc in each st around. (12 sts)
Rnd 3: 1 sc in the next st, inc in the next st. Repeat from * to * 6 times. (18 sts)
Rnd 4: 1 sc in the next 2 sts, inc in the next st. Repeat from * to * 6 times. (24 sts)
Rnd 5: 1 sc in the next 3 sts, inc in the next st. Repeat from * to * 6 times. (30 sts)
Rnd 6: 1 sc in the next 4 sts, inc in the next st. Repeat from * to * 6 times. (36 sts)

Finishing

Once you complete Round 6, do not chain. Remove your stitch marker and make a sl st into the first stitch of the final round to level off the edge. Fasten off your yarn, leaving a 4-inch tail. Use your tapestry needle to weave the tail through the back loops of the final round to secure it. Trim any excess yarn close to the fabric.

Care & Washing Instructions

Machine wash your cotton coasters on a gentle cycle with cold or warm water.
Lay the coasters flat on a clean towel to air dry, ensuring they are shaped into a perfect circle while damp.
If the coasters lose their shape over time, lightly steam them or spray them with a bit of water and press them under a heavy book for an hour.

Pro Tips & Common Mistakes to Avoid

Always use a stitch marker at the start of every round. Because this project is worked in continuous spirals, it is very easy to lose your place without a marker. Keep your tension firm. If you notice gaps between your stitches, try dropping down half a hook size to ensure the coaster remains solid enough to protect your surfaces from spills.

Weave your ends in by threading the needle through the stitches in two different directions rather than just one. This prevents the end from working itself loose during frequent washing. If you want a larger coaster, simply continue the pattern by adding rounds, increasing by 6 stitches each round until you reach your desired size; however, keep in mind this will require more yarn than the specified amount.

Frequently Asked Questions

Can I use a different yarn weight for this pattern?

Yes, you can use a lighter or heavier yarn, but remember that this will significantly change the final size of the coaster. Adjust your hook size accordingly to maintain a dense fabric.

Why do my coasters look hexagonal instead of round?

A slight hexagonal look is common when working increases in the same spot each round. To minimize this, you can shift the placement of your increases by starting a round with a single crochet rather than an increase.

Are these coasters safe to sell?

You are free to sell items made from this pattern, but it is standard practice to credit the designer. Please use your own photos of the finished product rather than photos from this guide.

Is cotton the only suitable fiber for these?

Cotton is recommended because it is heat-resistant and absorbent. Acrylic, polyester, or nylon yarns may not handle hot mugs well and can melt or lose their shape under extreme heat.
