Materials Needed

Before you begin your crafting journey, gather these essential supplies. The beauty of this pattern lies in its simplicity—only basic materials are required, and the worsted weight yarn ensures quick, satisfying progress.

• Yarn: Worsted weight cotton or acrylic yarn in three colors: seafoam green (main color), coral pink (fin flounce), and pearl white (shell embellishment). Approximately 100g total.
• Knitting Needles: US Size 6 (4.0 mm) straight or circular needles (circular recommended for the skirt portion).
• Crochet Hook: US Size D (3.25 mm) hook for the edging and shell motif.
• Notions: Stitch markers, tapestry needle for weaving in ends, small button (approx. 1/4 inch) for the back closure, and scissors.
• Gauge: 20 stitches and 28 rows = 4 inches in stockinette stitch. Always check your gauge to ensure a proper fit for your doll.

Step-by-Step Instructions

Follow these detailed instructions carefully. The pattern is divided into four main sections: the bodice, the skirt, the crochet fin flounce, and the shell embellishment. Take your time, and don't hesitate to refer back to the steps as needed.

Part 1: Knitting the Bodice (Worked Flat, Then Joined)

The bodice is knit flat in one piece, then shaped for the armholes and shoulders. This creates a seamless front and back.

1. Cast On: With seafoam green yarn, cast on 40 stitches onto your US Size 6 needles.
2. Garter Stitch Base (Rows 1-4): Knit every stitch across all 4 rows. This creates a sturdy, non-rolling edge for the top of the dress.
3. Buttonhole Row (Row 5): K2, *k2tog (knit two together), yo (yarn over), k1*; repeat from * to the last 2 stitches, k2. This creates a small, neat buttonhole on the right side of the bodice.
4. Garter Stitch Top (Rows 6-10): Knit all stitches for 5 more rows. This completes the top band.
5. Stockinette Body (Rows 11-20): Switch to stockinette stitch. This means you will knit on the right side (RS) and purl on the wrong side (WS). Work even for 10 rows.
6. Shape Armholes (Row 21 - RS): K8, bind off 8 stitches, K8, bind off 8 stitches, K8. You will now have three separate sections on your needle: 8 stitches for the left front, 8 for the back, and 8 for the right front.
7. Work Shoulder Straps: Work each 8-stitch section separately. For each strap, work in stockinette stitch for 6 rows. After 6 rows, bind off all 8 stitches. Repeat this for the other front strap and the back strap.
8. Seam the Shoulders: Use your tapestry needle and a length of seafoam yarn to sew the front straps to the back straps at the shoulders. Weave in the ends.

Part 2: Knitting the Flared Skirt (Worked in the Round)

This is where the magic happens! The skirt is picked up from the bodice and knit in the round, using simple yarn-over increases to create a dramatic A-line flare.

1. Pick Up Stitches: With the right side of the bodice facing you, use your circular needle to pick up and knit 40 stitches around the bottom edge of the bodice. Place a stitch marker to mark the beginning of the round.
2. Join in the Round: Carefully join, being sure not to twist your stitches.
3. Increase Round 1: *K1, yo*; repeat from * to end of round. You will now have 80 stitches on your needle.
4. Knit Even (Rounds 2-4): Knit all stitches for 3 rounds. The yarn overs from the previous round will create small eyelet holes, forming the lace pattern.
5. Increase Round 2: *K2, yo*; repeat from * to end. You will now have 120 stitches.
6. Knit Even (Rounds 6-8): Knit all stitches for 3 rounds.
7. Increase Round 3: *K3, yo*; repeat from * to end. You will now have 160 stitches.
8. Knit Even (Rounds 10-12): Knit all stitches for 3 rounds.
9. Increase Round 4: *K4, yo*; repeat from * to end. You will now have 200 stitches.
10. Knit Even (Rounds 14-16): Knit all stitches for 3 rounds.
11. Increase Round 5: *K5, yo*; repeat from * to end. You will now have 240 stitches.
12. Knit Even (Rounds 18-20): Knit all stitches for 3 rounds.
13. Increase Round 6: *K6, yo*; repeat from * to end. You will now have 280 stitches.
14. Knit Even (Rounds 22-24): Knit all stitches for 3 rounds.
15. Increase Round 7: *K7, yo*; repeat from * to end. You will now have 320 stitches.
16. Knit Even (Rounds 26-28): Knit all stitches for 3 rounds.
17. Bind Off: Bind off all stitches loosely. A loose bind-off is crucial to maintain the flowy, flared edge of the skirt. You can use a larger needle to bind off if needed.

Part 3: Crocheting the Fin Flounce (Coral Pink Edging)

This delicate scalloped edge adds the perfect mermaid fin touch. Using your US Size D crochet hook and coral pink yarn, follow these steps.

1. Join Yarn: Insert your hook into any stitch along the bind-off edge of the skirt. Pull up a loop of coral pink yarn and chain 1.
2. Round 1 (Single Crochet): Work 1 single crochet (sc) in each stitch around the entire edge. Join with a slip stitch to the first sc. This creates a stable base for the flounce.
3. Round 2 (Chain Loops): *Chain 5, skip 2 sc, work 1 sc in the next sc*; repeat from * around the entire edge. Join with a slip stitch to the first sc. You will have a series of chain-5 loops.
4. Round 3 (Scallops): In each chain-5 space from the previous round, work the following: 3 double crochet (dc), chain 2, 3 double crochet (dc). This creates a beautiful shell or scallop shape. Work this in every loop around. Fasten off and weave in the end.

Part 4: Creating the Shell Bodice Embellishment

This tiny pearl-white shell is the crowning jewel of the dress, adding a touch of elegance to the center front.

1. Magic Ring: With pearl white yarn, create a magic ring.
2. Round 1: Work 6 single crochet (sc) into the ring. Pull the tail to close the ring tightly. Join with a slip stitch to the first sc.
3. Round 2 (Increase): Work 2 sc in each sc around. You will have 12 sc. Join with a slip stitch.
4. Round 3 (Increase): *Sc in the next sc, 2 sc in the next sc*; repeat from * around. You will have 18 sc. Fasten off, leaving a long tail for sewing.
5. Attach to Bodice: Use the yarn tail and a tapestry needle to sew the shell motif securely to the center front of the bodice, just below the neckline. Weave in the end.

Finishing Touches

Your mermaid dress is almost complete! These final steps will ensure a polished, professional look.

1. Weave in All Ends: Use your tapestry needle to carefully weave in any remaining yarn ends on the inside of the dress.
2. Sew the Button: Sew a small button on the back neckline of the bodice, opposite the buttonhole you created in Row 5. This will be the closure for the dress.
3. Block the Skirt: Lightly steam block the skirt to open up the lace pattern and give it a beautiful, flowing drape. Be careful not to flatten the crochet scallops. Pin the skirt out to your desired shape and steam gently.

And there you have it—a stunning, handcrafted Coral Cascade Mermaid Doll Dress! This project is a wonderful way to practice increases, lace patterns, and simple crochet edging. The result is a one-of-a-kind gown that will spark imaginative play and be treasured for years. Happy knitting!
