Introducing the Tidal Lace Baby Blanket

This ethereal, modern heirloom features a unique undulating lace pattern that mimics the gentle shore, making it a timeless piece for any contemporary nursery. Knit in a soft, breathable cotton blend, this blanket is as practical as it is beautiful. Whether you are a seasoned lace knitter or a confident beginner looking for a rewarding challenge, this pattern will guide you to create a cherished keepsake.

Materials Needed

To create this ocean-inspired blanket, you will need the following materials. Using the exact yarn or a similar light worsted weight cotton blend will ensure the best drape and stitch definition.

Yarn

• Brand: Cascade Yarns Ultra Pima Fine (100% Pima Cotton; 136 yds / 50g)
• Quantity: 6 skeins
• Color: 'Seafoam' (a soft, pale green-blue) or any light worsted weight cotton blend of your choice.

Needles & Notions

• Needle: US Size 6 (4.0 mm) 32-inch circular knitting needle (used for working flat; the long cord holds the many stitches comfortably).
• Notions: Tapestry needle for weaving in ends, blocking pins, and a tape measure.

Gauge

• Gauge: 20 stitches and 28 rows = 4 inches in stockinette stitch, after blocking.
• Tip: Always knit a gauge swatch and block it before starting to ensure your finished blanket matches the intended size.

Step-by-Step Instructions

This pattern is worked flat from the bottom up. The lace pattern is a 12-row repeat that creates a gentle wave effect. A garter stitch border (knit every row) is worked on all edges for a clean, non-curling finish. For a neat selvedge edge, always slip the first stitch of every row purlwise with yarn in front.

Finished Size

Approximately 36 inches wide x 40 inches long (after blocking).

Begin Lace Pattern

Note: The first and last 4 stitches of every row form the side borders and are always knit (except the first stitch which is slipped). The lace pattern is worked between these borders.

Row 1 (RS): Slip 1 purlwise wyif, k3 (border), *yo, ssk, k1, k2tog, yo, k1, yo, ssk, k1, k2tog, yo, k1; rep from * to last 4 sts, k4 (border).

Row 2 (WS): Slip 1 purlwise wyif, k3, purl to last 4 sts, k4.

Row 3: Slip 1 purlwise wyif, k3, *k1, yo, ssk, k1, k2tog, yo, k3, yo, ssk, k1, k2tog, yo; rep from * to last 4 sts, k4.

Row 4: Same as Row 2.

Row 5: Slip 1 purlwise wyif, k3, *k2, yo, ssk, k1, k2tog, yo, k1, yo, ssk, k1, k2tog, yo, k1; rep from * to last 4 sts, k4.

Row 6: Same as Row 2.

Row 7: Slip 1 purlwise wyif, k3, *k1, k2tog, yo, k1, yo, ssk, k1, k2tog, yo, k1, yo, ssk, k1; rep from * to last 4 sts, k4.

Row 8: Same as Row 2.

Row 9: Slip 1 purlwise wyif, k3, *k2tog, yo, k3, yo, ssk, k1, k2tog, yo, k3, yo; rep from * to last 4 sts, k4.

Row 11: Slip 1 purlwise wyif, k3, *k1, yo, ssk, k1, k2tog, yo, k1, yo, ssk, k1, k2tog, yo, k1; rep from * to last 4 sts, k4.

Row 12: Same as Row 2.

Repeat Rows 1-12 until the blanket measures approximately 38 inches from the cast-on edge, ending after a Row 12 (WS).

Border (Garter Stitch)

Knit 6 rows. (This creates the top garter stitch border.)

Bind Off

Bind off loosely on the next RS row (knitwise). Use a stretchy bind-off method if desired to maintain flexibility. Weave in all ends with a tapestry needle.

Blocking

Blocking is essential for lace to open up the pattern and achieve the correct dimensions. Soak the blanket in lukewarm water with a gentle wool wash for 20 minutes. Gently squeeze out excess water (do not wring). Lay flat on a towel, roll up to remove more moisture, then unroll and pin to finished dimensions (36 x 40 inches), stretching the lace points gently. Allow to dry completely.

Once dry, your Tidal Lace Baby Blanket is ready to be gifted or treasured. The soft, airy texture and gentle wave pattern will bring a touch of coastal calm to any little one's world.
