Chapin Jumper Knitting Pattern

Chapin Jumper in Berroco Providence

What is Being Made

The Chapin Jumper is an advanced-level knitted sweater designed by Alison Green from Book #409. This pullover-style jumper is available in eight sizes ranging from 34½" to 62¼" bust measurement, with finished lengths from 22" to 25½" depending on size. The garment is shown in the 38¼" size and features a refined construction suitable for experienced knitters.

Knitting Techniques Used

This pattern employs several intermediate to advanced knitting techniques that contribute to its experienced skill level designation. The construction utilizes circular knitting worked in the round using both 16" and 29" circular needles, which allows for seamless construction and even stitch distribution. The pattern incorporates tubular cast-on, a specialized casting-on method that creates a professional, finished edge. Additional techniques include double decreases for shaping and stitch manipulation, as well as cable needle work for textural interest. The garment is worked with positive ease of 2–4" for a comfortable, relaxed fit.

Stitches Used

The primary stitch pattern is the Seeded Rib Stitch, which creates a textured, reversible fabric with alternating knit and purl stitches. The pattern provides instructions for both odd and even stitch counts of this stitch. Special abbreviations include L-Dec2 (Left Double Decrease), worked as slip 1 knitwise, knit 2 together, pass slipped stitch over, and R-Dec2 (Right Double Decrease), worked as slip slip knit with additional stitch manipulation. These decreases are essential for shaping the garment body and creating structured design lines.

Materials: Yarn, Needles, and Notions

The Chapin Jumper is knitted with Berroco Providence yarn in colorway #1119 Water Fire. Yarn requirements range from 8 to 15 balls (50 grams each) depending on the finished size selected. The pattern calls for circular needles in size 5 (3.75 mm) as the primary working needle for the body, with size 3 (3.25 mm) double-pointed needles for ribbed edgings and cuffs. A cable needle is required for cable stitch work. Additional notions include stitch markers (with one in a contrasting color to mark the beginning of round) and waste yarn for the tubular cast-on method and for holding stitches during construction. The recommended gauge is 22 stitches and 32 rows over 4 inches in Seeded Rib Stitch using the larger needles.
