The Sunburst Mosaic Blanket: A Free Knitting Pattern for a Textured, Color-Blocked Throw

Wrap Yourself in Sunshine: The Sunburst Mosaic Blanket

Imagine curling up under a blanket that feels like a warm, sun-drenched mosaic floor. The Sunburst Mosaic Blanket is exactly that—a modern heirloom piece that brings a burst of color and texture to any room. Using a unique mosaic knitting technique, you'll create interlocking diamond shapes and bold stripes that look far more complex than they actually are. This free pattern is designed for adventurous beginners who want to try something stunning without the stress of carrying multiple colors per row. Let's dive in and create something beautiful together.

Materials Needed

Before you begin, gather these supplies. Using the exact yarn weight and needle size is crucial for achieving the correct gauge and finished size (approximately 50 inches by 60 inches).

• Yarn: Worsted weight (#4) yarn in 4 colors:
  • Color A (Sunshine Yellow) – 600g
  • Color B (Terracotta) – 500g
  • Color C (Cream) – 400g
  • Color D (Deep Teal) – 300g
• Needle: US 8 (5.0 mm) circular knitting needle, 32-inch or longer (to accommodate the large number of stitches)
• Notions: Stitch markers (optional), tapestry needle for weaving in ends, blocking pins and mats

Gauge & Abbreviations

Gauge: 18 stitches and 24 rows = 4 inches in Stockinette stitch (knit on RS, purl on WS). Always check your gauge before starting.

Abbreviations:

• K: Knit
• P: Purl
• Sl: Slip stitch purlwise (as if to purl) with yarn in back (wyib) on right-side rows, and with yarn in front (wyif) on wrong-side rows

Step-by-Step Instructions

Pattern Notes

This blanket is worked flat in rows from the bottom up. The mosaic technique means you only work with one color per row. You will slip stitches from the previous row to create the pattern—no stranding or carrying yarn across the back. Read all charts from right to left for right-side (RS) rows, and left to right for wrong-side (WS) rows. The design is fully charted below in written form.

Border (Worked in Color A)

Cast on 160 stitches with Color A (Sunshine Yellow).

• Rows 1-6: Knit all stitches. This creates a garter stitch border.

Work these 4 rows for a total of 60 rows (15 repeats of the diamond motif).

• Row 1 (RS, Color B – Terracotta): K1 (edge), *K1, Sl1, K3, Sl1, K1, Sl1, K3, Sl1, K1, Sl1* repeat from * to * across, end with K1 (edge).

• Row 1 (RS, Color D – Deep Teal): K1, *K1, Sl1, K3, Sl1, K1, Sl1, K3, Sl1, K1, Sl1* repeat from * to *, end with K1.

Top Border

Switch back to Color A (Sunshine Yellow).

• Rows 1-6: Knit all stitches (garter stitch).
• Bind off loosely: Use a stretchy bind-off (like the knitted bind-off or Jeny's surprisingly stretchy bind-off) to ensure the edge doesn't pull in.

Finishing

Weave in all ends carefully using a tapestry needle. Block the blanket to open up the mosaic pattern and ensure even tension. To block, soak the blanket in lukewarm water with a gentle wool wash, gently squeeze out excess water (do not wring), lay flat on blocking mats, and pin to the desired dimensions. Allow to dry completely before removing pins.

Congratulations! You've just created a stunning, textured throw that will be cherished for years. The interplay of sunshine yellow, terracotta, cream, and deep teal creates a warm, geometric masterpiece that looks like it belongs in a design magazine. Enjoy your new favorite cozy companion!
