Wrap yourself in the warmth of a crackling fire with this stunning mosaic knit blanket, featuring a geometric flame-inspired motif in rich autumnal tones. This modern heirloom piece is surprisingly simple to knit, using slipped stitches to create a complex-looking pattern that's perfect for cozy evenings. The interlocking diamond and zigzag shapes evoke the flickering flames of a hearth, while the smooth, dense texture with subtle vertical ridges catches the light beautifully. Whether you're a seasoned knitter looking for a mindful project or a confident beginner ready for a rewarding challenge, this blanket is designed to become a cherished staple in your home.

This pattern is worked flat in one piece, making it highly portable and easy to manage. The mosaic technique is a fantastic way to create intricate, multi-colored designs without the hassle of stranding or intarsia—you simply work with two colors per row and slip stitches from the row below to build the geometric pattern. The result is a fabric that is both visually striking and wonderfully warm, perfect for draping over a sofa or curling up with on a chilly evening.

Materials Needed

Before you begin, gather the following materials to ensure a smooth and enjoyable knitting experience:

• Yarn: Worsted weight yarn in 3 colors:
  • Color A (Ember – burnt orange): Approximately 1200 yards
  • Color B (Ash – warm grey): Approximately 800 yards
  • Color C (Cream – off-white): Approximately 600 yards
• Needles: US Size 8 (5.0 mm) knitting needles (or size needed to obtain gauge)
• Notions: Tapestry needle for weaving in ends

Gauge: 18 stitches and 24 rows = 4 inches in stockinette stitch. Gauge is not critical for this pattern, but consistency will ensure even sizing. If you tend to knit loosely or tightly, adjust your needle size accordingly to achieve a fabric you love.

Step-by-Step Instructions

This blanket is worked flat in one piece. The mosaic pattern is created by working with two colors per row, slipping stitches from the previous row to create the geometric design. Read all instructions carefully before beginning.

Special Stitches

• Sl1 wyib: Slip 1 stitch purlwise with yarn in back.
• Sl1 wyif: Slip 1 stitch purlwise with yarn in front.

Pattern Notes

• The blanket is worked in a multiple of 8 stitches + 2 edge stitches.
• Each row is worked with two colors: the main color (MC) and a contrasting color (CC).
• The mosaic pattern is created by alternating colors every two rows and slipping stitches from the row below.

Cast On

With Color A, cast on 122 stitches loosely. A long-tail cast-on works beautifully here, but any stretchy cast-on method you prefer will do.

Border (worked in garter stitch)

Rows 1-6: Knit all stitches with Color A. This creates a clean, sturdy edge that will frame your mosaic pattern beautifully.

Repeat Rows 3-18 until the blanket measures approximately 60 inches from the cast-on edge, ending with a Row 18 repeat. This will give you a beautiful, generous throw size. If you prefer a shorter lap blanket, you can stop at 50 inches—the pattern is wonderfully adaptable.

Border

With Color A, knit 6 rows of garter stitch (knit every row). This mirrors the cast-on border and creates a polished, finished look.

Bind Off

Bind off loosely with Color A. A stretchy bind-off, such as the knit-two-together bind-off or the Jeny's surprisingly stretchy bind-off, is recommended to ensure the edge doesn't pull or pucker. Weave in all ends with a tapestry needle, being careful to secure them well within the slipped stitches so they remain hidden.

Block gently to even out the stitches and enhance the geometric pattern. A light steam block or a soak in lukewarm water with a gentle wool wash will work wonders—lay flat to dry, shaping to your desired dimensions. Once dry, your Ember & Ash Mosaic Knit Blanket is ready to grace your home with its cozy, flame-inspired beauty.

Enjoy the process and the stunning result—this is a project you'll be proud to snuggle under for years to come.
