Lang PTO31-05 Sweater Jumper Knitting Pattern

Lang PTO31-05 Sweater

What is Being Made

The Lang PTO31-05 is a knitted sweater available in sizes S–M and L–XL. This garment features a classic pullover construction with finished bust measurements of 47¼ inches (120 cm) for size S–M and 52¾ inches (134 cm) for size L–XL. The sweater has a total length of 22 inches (56 cm) for the smaller size and 22¾ inches (58 cm) for the larger size, making it a versatile everyday knit suitable for layering or wearing as a standalone piece.

Knitting Techniques Used

This sweater employs a bottom-up construction method, meaning the garment is knitted starting from the lower edges and working upward toward the shoulders and neckline. The pattern uses both flat knitting and working in the round techniques, allowing knitters to choose their preferred method for different sections. The finished pieces are seamed together, which creates clean, professional-looking joins between the front, back, and sleeve sections. Simultaneous shaping of the shoulders and neckline is required, demanding careful attention to stitch counts and bind-off sequences on both sides of the garment.

Stitches and Stitch Patterns

The primary stitch pattern used throughout this sweater is Rib Stitch, which provides excellent elasticity and a refined, fitted appearance. The Rib Stitch is worked differently depending on the construction method:

• Flat Rib Stitch: Worked on an even number of stitches using alternating knit and purl stitches (K1, P1) across every row, creating vertical ribbed columns when viewed from the front.
• Rib Stitch in the Round: Every round alternates knit and purl stitches (K1, P1), maintaining the same visual effect but worked circularly.

The ribbed texture provides functional stretch and recovery, making the sweater comfortable to wear and helping it maintain its shape through repeated wear and washing. The neckline shaping involves strategic bind-offs and slip stitches to waste yarn, creating a finished neck opening with proper proportions for the garment sizes.

Materials and Tools

This sweater is designed to be knitted with LANGYARNS CLOUD, an extra-fine merino wool blend that is mulesing-free and reinforced with nylon for durability. The yarn is available in the color Bordeaux-green-blue (color number 1077.0005). Yardage requirements are 500 grams (approximately 5 balls) for size S–M and 600 grams (approximately 6 balls) for size L–XL.

The pattern requires ADDI knitting needles in two sizes: US 15 (10mm) needles for the ribbed sections and US 17 (12mm) needles for the main body of the sweater. Additionally, one short circular needle in US 15 (10mm) is needed, likely for working the neckline or other small circumference sections. The use of different needle sizes creates gauge variation that enhances the fit and drape of the finished garment.
