Light Up Jumper

Light-Up Jumper is a textured crochet sweater with a relaxed fit and a soft, structured look. The vertical rib effect created by working in the back loop only gives the surface a defined texture, while the simple shape keeps the design wearable and easy to style. The wide sleeves and clean neckline balance the heavier fabric and give the jumper a modern handmade feel. This design focuses on repetition and structure rather than complexity. The combination of slip stitches, double crochet, and taller stitches creates a fabric that feels dense and warm without becoming stiff. The consistent use of back loop only adds depth and makes the texture stand out clearly across the entire garment. Light-Up Jumper is crocheted lengthwise in one piece, beginning at the sleeve and continuing across the body to the second sleeve. The front and back sections are shaped by chaining between sections, and the entire piece is then sewn together to form the final garment. The sleeves are integrated into the construction, and the jumper is finished with a simple round of double crochet at the neckline for a clean edge. **Level** Beginner to intermediate **Sizes** XS (S) M (L) XL (XXL) **Measurement**s Length: 50 (55) 55 (55) 60 (62) cm Width: 49 (49) 56 (63) 63 (68) cm Sleeve length: approx. 75 cm **Materials** Crochet hook: 5.50 mm (or size needed to meet gauge) **Yarn** Infinity Hearts Lily 70% Cotton, 30% SW Merino Wool 50 g = approx. 100 m Sample shown in colour 12 (light green) **Yarn requirements** 450 (500) 550 (650) 750 (850) g Approx. 900 (1000) 1100 (1300) 1500 (1700) metres **Gauge** 4 stitches (BLO) = 5 cm width 7 rows (BLO) = 5 cm length Light-Up Jumper is a textured crochet sweater with a relaxed fit and a soft, structured look.

The lengthwise build creates a natural drape across the body, while the integrated sleeves reduce the need for complex shaping. The pattern is repetitive and structured, making it suitable for crocheters who prefer a steady rhythm with visible progress. Small finishing details, like the neckline edging, complete the design without adding unnecessary steps. Design by Lisette Lannerhag Share your finished make with #lysesweater #ritohobby
