Fred the Sea Turtle is a soft, palm-sized companion that sits comfortably on a desk or tucked into a child’s backpack. This little friend features a rounded shell and four simple flippers, giving it a friendly appearance that appeals to anyone who enjoys sea creatures. You will find that the construction relies on basic shaping techniques that remain approachable even if you have only been holding a hook for a few weeks. The project uses standard single crochet stitches worked in the round, resulting in a firm fabric that keeps its shape well over time. Making this turtle provides a sense of accomplishment because it comes together in just an afternoon of stitching at your own pace.

Why You’ll Love This Pattern

This beginner-friendly crochet coaster pattern uses a simple, repetitive stitch pattern that makes it ideal for practicing tension control. Because each coaster requires only a small amount of yarn, it is the perfect project to utilize leftover cotton scraps from larger baskets or market bags. You can easily complete a full set of four in a single evening, which makes them an excellent choice for last-minute housewarming gifts or craft market inventory. The dense texture created by the moss stitch provides a sturdy heat-resistant barrier for tabletops.

These coasters worked up incredibly fast and the moss stitch gives them such a nice, professional finish that does not curl at the edges.

Pattern Overview & Skill Level

Skill Level: Beginner
Approximate Time: 30 minutes per coaster
Construction: Worked in flat rows back and forth, beginning with a foundation chain.
Finished Dimensions & Sizing: Approximately 4 inches by 4 inches square.

Materials & Supplies Needed

Yarn: Worsted weight (#4) 100% cotton yarn, approximately 20 yards per coaster. Cotton is preferred over acrylic as it is more heat-resistant and absorbent.
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: You may use a bamboo-cotton blend for a softer feel, though this may require tighter tension to maintain the 4-inch square shape. Avoid wool for coasters, as it can felt if exposed to moisture and heat repeatedly.

Step-by-Step Pattern Instructions

Main Body

The coaster is worked in rows. You will turn your work at the end of every row.

Row 1: Ch 17. Sc in the 4th ch from the hook. *Ch 1, sk 1 ch, sc in the next ch. Repeat from * across until the end. Turn. (8 sc, 7 ch-spaces)
Row 2: Ch 2 (counts as ch 1), sk the first sc, sc in the first ch-1 space. *Ch 1, sk the next sc, sc in the next ch-1 space. Repeat from * across, ending with a sc in the turning chain space. Turn. (8 sc, 7 ch-spaces)
Rows 3-14: Repeat Row 2 until the piece measures approximately 4 inches square.

Border & Finishing

To give the coaster a polished look, work a round of single crochet around the perimeter.

Round 1: Ch 1, work sc evenly around all four sides of the coaster. Place 3 sc in each corner to ensure the edges lie flat without pulling. Join with a sl st to the first sc.
Finishing: Fasten off, leaving a 6-inch tail. Use your tapestry needle to weave the yarn tail through the stitches on the back side of the coaster to secure it.

Care & Washing Instructions

Machine wash on a delicate cycle in cool water to prevent color bleeding or shrinking.
Lay the coaster flat on a towel to air dry, reshaping it with your hands while damp.
Do not iron directly on the cotton surface, as this may crush the texture of the stitches.

Pro Tips & Common Mistakes to Avoid

Consistent tension is vital for this pattern; if your stitches are too loose, the coaster will feel flimsy and lose its square shape. Always use a stitch marker at the start of your rows to ensure you do not accidentally drop stitches at the edges, which is the most common mistake for beginners. When weaving in your ends, run the needle through the center of the stitches rather than over the surface so the tail remains invisible. If you wish to make a larger coaster, increase your initial chain by an even number; remember that each additional inch in width will increase your yarn consumption by approximately 15 percent.

Frequently Asked Questions

Can I use acrylic yarn for these coasters?

While possible, cotton is highly recommended. Acrylic yarn can melt or become deformed if a very hot mug is placed directly on it.

How do I adjust the size of the coaster?

Simply add or subtract chains in multiples of two for your foundation row. Always maintain an odd number of total chains to keep the moss stitch pattern aligned.

Is this pattern suitable for someone who has never held a crochet hook?

Yes, this is an ideal first project. It only requires the single crochet stitch and chaining, which are the fundamental building blocks of almost all crochet projects.

May I sell the coasters I make from this pattern?

Yes, you may sell finished items made from this design. I kindly ask that you credit the pattern to this website if you list them in an online shop.
