Why You’ll Love This Pattern

This beginner-friendly crochet coaster set uses the moss stitch to create a dense, squishy fabric that protects tabletops from moisture rings. Because the pattern relies on a simple one-row repeat, it is easy to pick up and put down, making it a reliable project for busy evenings. You only need a small amount of cotton yarn for each piece, which helps clear out leftover scraps from larger projects. The resulting coasters are durable enough for daily use and make thoughtful, handmade gifts for housewarming parties or holidays.

I finished a set of four in a single afternoon while watching a movie. The texture is thick enough to be functional and they wash up perfectly in the machine.

Pattern Overview & Skill Level

Skill Level: Beginner
Approximate Time: 30 minutes per coaster
Construction: Worked in flat rows, turning at the end of each row, with a final round of single crochet to square off the edges.
Finished Dimensions & Sizing: 4 inches by 4 inches

Materials & Supplies Needed

Yarn: Worsted weight (#4) 100% cotton yarn. Approximately 20 yards per coaster. Cotton is necessary for heat resistance and absorbency.
Hook Size: 5.0 mm (H-8) crochet hook.
Notions needed: Tapestry needle for weaving in ends, scissors, and a measuring tape.
Safe yarn substitutions: Acrylic yarn can be used for decorative purposes, but it will not absorb condensation as effectively as cotton. Wool is not recommended for coasters as it can felt if it gets wet frequently.

Step-by-Step Pattern Instructions

Coaster Body

Row 1: Ch 16. Sc in 4th ch from hook, ch 1, sk 1 ch, sc in next ch repeat from * to * until the end. Turn. (8 sc, 7 ch-1 spaces)
Row 2: Ch 2, sc in the first ch-1 space. Ch 1, sk next sc, sc in next ch-1 space repeat from * to * across, ending with a sc in the turning ch-space. Turn. (8 sc, 7 ch-1 spaces)
Row 3-14: Repeat Row 2 until the piece measures approximately 4 inches in height.

Border & Finishing

After reaching the desired height, you will work a round of single crochet around the perimeter to clean up the edges.

Rnd 1: Ch 1, work sc evenly around the entire square. Work 3 sc into each corner to ensure the fabric lies flat without curling.
Finishing: Join with a sl st to the first sc. Fasten off leaving a 6-inch tail. Weave in all loose ends securely using the tapestry needle.

Care & Washing Instructions

Machine wash on a gentle cycle in cold water with mild detergent.
Lay the coasters flat on a clean towel to dry to maintain their square shape.
If the coasters lose their shape, dampen them slightly and press them flat with a warm iron to block them into a perfect square.

Pro Tips & Common Mistakes to Avoid

Maintain consistent tension throughout your rows. If your stitches are too tight, the coaster will be stiff; if they are too loose, the fabric will be flimsy and less effective as a coaster.
Use a stitch marker at the start of your border round so you know exactly where to join your slip stitch.
Weave your ends back and forth in three different directions within the border stitches to ensure they remain hidden and secure after repeated washing.
You can adjust the size by chaining an even number to start. Each chain added or removed changes the finished width by approximately 0.5 inches. Keep in mind that larger sizes will require more yarn.

Frequently Asked Questions

Can I use a different yarn weight for this pattern?

Yes, but you will need to adjust your starting chain count. If using a thinner yarn, such as DK weight, you will need to start with more chains to reach the 4-inch width. If using a thicker bulky yarn, reduce the number of chains.

Why do my edges look wavy?

Wavy edges usually occur when too many stitches are placed in the corners or along the straight sides during the border round. Ensure you are only placing 3 single crochets in each corner and working only one stitch per row end along the sides.

Is this pattern suitable for complete beginners?

Yes, this is an excellent starter project. It uses only the chain stitch and single crochet, providing plenty of practice for maintaining consistent tension without the complexity of shaping or color changes.

Can I sell the coasters I make using this pattern?

You are welcome to sell finished items made from this pattern as long as you credit the original design and use your own photographs. You may not distribute or sell the written pattern itself.

Your finished fish looks great perched on a desk or tucked into a child’s toy bin, showing off those distinct stripes you carefully worked into the rows. If you want to experiment, try using a fuzzy mohair blend to give your creation a softer, more realistic look or scale it up with bulky yarn for a larger huggable version.
