Bright Geometric Blanket in Deramores Studio Chunky Acrylic by Sarah Murray

The Bright Geometric Blanket is a beginner knitting pattern designed by Sarah Murray, a freelance knitting and crochet designer based in Cornwall, UK. Published by Deramores and available as a downloadable PDF, this pattern produces a striking, colour-blocked blanket measuring 90cm x 110cm. The finished piece is assembled from individual knitted squares and half-squares arranged in a bold geometric layout, making it an ideal project for those new to knitting who want to build confidence while creating something visually impressive for the home.

Design Overview and Construction

Rather than knitting the blanket in a single large piece, this pattern uses a modular construction method: individual squares and half-squares are knitted separately and then sewn together following a chart or photograph guide. This approach makes the project highly manageable for beginners, as each piece is small and straightforward. It also makes the blanket easily scalable — Sarah Murray notes in the pattern that working more or fewer squares allows knitters to adjust the finished size to suit their needs.

The geometric effect is achieved through the careful arrangement of large squares and half squares in four contrasting colours, creating a bright, modern aesthetic. Once the pieces are assembled, upper and lower borders are added to finish the blanket neatly. An optional pom pom maker is listed as an extra, suggesting decorative pom pom embellishments can be added for a playful finishing touch.

Stitches and Techniques Used

The primary stitch used throughout this pattern is double moss stitch (also known as seed stitch in some traditions), a classic reversible texture stitch that alternates knit and purl stitches across rows in a specific sequence. In this pattern, double moss stitch is worked as follows:

• Row 1 (RS): *K1, P1; repeat from * to end
• Row 2: As Row 1
• Row 3: *P1, K1; repeat from * to end
• Row 4: As Row 3

These four rows form the repeating pattern unit. Double moss stitch creates a dense, slightly textured fabric with a neat, even appearance on both sides — making it particularly well suited to a blanket, which is visible from either face. Because the stitch is fully reversible, there is no distinct wrong side, giving the finished blanket a polished look throughout.

Stitches referenced in the pattern abbreviations include K (Knit) and P (Purl) — the two fundamental knitting stitches. Knitters familiar with casting on and working basic knit and purl stitches will have everything they need to complete this project. The thumb method cast-on is specified for starting each square, casting on 26 stitches per large square.

Additional techniques involved include:

• Modular knitting — working individual squares and half-squares as separate pieces
• Seaming — sewing completed squares together using a chart as a guide
• Border knitting — working upper and lower borders to finish the assembled blanket
• Pom pom making — optional decorative addition using a pom pom maker

Tension

The stated tension for this pattern is 13 stitches and 19 rows to 10cm x 10cm (4 x 4 inches) using 6mm needles over double moss stitch. Achieving the correct tension is important for ensuring each square knits up to the right size so that the geometric layout aligns correctly when the pieces are sewn together.

Materials

The blanket is knitted in Deramores Studio Chunky acrylic yarn, used across four colourways to create the geometric colour-block design. The yarn quantities required are:

• 5 x 100g balls in Frost (Yarn A)
• 4 x 100g balls in Jade (Yarn B)
• 2 x 100g balls
