Sumatra Jumper in Adriafil Memphis & New York – Free Knitting Pattern Summary

The Sumatra Jumper is a stylish, relaxed-fit pullover sweater designed for knitters who enjoy working with bold, textured yarns and simple stripe sequences. This free downloadable PDF pattern from Adriafil Yarns produces a classic jumper with a striped body and sleeves, combining two distinctive Adriafil yarn types to create rich visual contrast and a satisfying knitted fabric.

What Is Being Made

The pattern constructs a complete pullover jumper — known in some regions as a sweater — worked in separate pieces that are seamed together. The garment includes a back, a front, and two sleeves, each featuring a coordinated stripe sequence. The finished jumper is designed with a relaxed silhouette, making it a versatile wardrobe piece suitable for cooler seasons.

Materials Used

The pattern calls for two specific Adriafil Yarns products used in combination:

• Adriafil Memphis in green, colour no. 58 — 300 g total. Memphis is an aran to chunky weight yarn that provides the primary body of the fabric.
• Adriafil New York in colour no. 83 — 100 g total. New York is used as the contrasting stripe yarn, adding textural and tonal interest throughout the garment.
• Knitting needles in sizes no. 4 and no. 5 are required, with the smaller needles used for the border sections and the larger needles for the main body of the fabric.
• A crochet hook in size 4.00 mm is also listed among the materials, likely used for finishing, seaming, or edging details.

Techniques Used

The Sumatra Jumper employs a range of fundamental and intermediate knitting techniques, making it an excellent project for knitters who are comfortable with basic construction but want to explore stripe patterning and simple shaping:

• Stripe sequencing — The pattern alternates between Memphis and New York yarns in a structured repeat: 2 rows of Memphis, then a repeating sequence of 4 rows New York and 4 rows Memphis, carried through multiple repeats before ending with Memphis. This creates a rhythmic, easy-to-follow striped fabric.
• Increasing and decreasing — Sleeve shaping involves increasing 1 stitch at each end every 2 rows, 8 times, creating a gradual taper toward the upper arm. The body features decreasing 2 stitches at each end every 2 rows, 6 times to shape the sides before the armhole.
• Armhole shaping — Side stitches are bound off to create the armhole opening, a classic set-in or drop-shoulder style construction.
• Border knitting — A border section is worked on both the body and sleeves using the smaller no. 4 needles and Memphis yarn before transitioning to the larger needles for the main fabric.
• Casting on and binding off — Standard cast-on and bind-off methods are used throughout, including binding off side stitches for armhole shaping.
• Finishing with a crochet hook — The inclusion of a 4.00 mm crochet hook suggests crochet-based finishing techniques, which are common for neat edge work or joining seams in knitted garments.

Stitches Used

• Knitted stitch (stockinette/stocking stitch) — The main body of the jumper, including the sleeves, is worked in knitted stitch, which creates a smooth, classic fabric that showcases the stripe pattern effectively.
• Border stitch — A border pattern is worked at the cast-on edges of both the body pieces and the sleeves, providing a neat, structured hem finish.

Pattern Construction Details

The back and front are worked identically, which simplifies the construction process. The sleeve begins with a cast-on of 72, 76, or
