Berroco Bloomfield Jumper Knitting Pattern

Berroco Bloomfield Knit Sweater

What is Being Made

The Bloomfield is a knit sweater designed by Amy Christoffers for intermediate-level knitters. This garment is constructed in the round from the bottom up, creating a seamless pullover sweater with finished bust measurements ranging from 35 inches to 65½ inches across nine size options. The sweater features a modest positive ease of 2–4 inches for comfortable wear, with length measurements varying from 21 inches to 24 inches down the center back depending on size selection.

Knitting Techniques and Construction Methods

The Bloomfield employs several key knitting techniques characteristic of modern sweater construction. The garment is worked entirely in the round, eliminating the need for seaming and creating a seamless finished piece. A distinctive feature of this design is the use of two yarns held together throughout—one strand each of Berroco Providence and Berroco Aerial are worked simultaneously to create the fabric. This technique adds visual interest and texture while achieving the specified gauge. The pattern requires working with multiple needle sizes and types, including both circular needles of different lengths and double-pointed needles for smaller circumferences, allowing knitters to transition smoothly from the body to the sleeves and neckline.

Stitches and Stitch Patterns

The primary stitch used in the Bloomfield is Stockinette Stitch (St st), which creates a smooth, classic knit fabric. The pattern is worked at a gauge of 21 stitches and 28 rounds per 4 inches on the larger needle size when using one strand each of Providence and Aerial held together. This gauge specification is essential for achieving accurate finished measurements and proper garment fit.

Yarn and Materials

The Bloomfield pattern calls for two complementary Berroco yarns that are worked together throughout the project. Berroco Providence is used as the primary yarn, requiring between 7 and 13 balls depending on size, with the color shown being #1115 Rosecliff. Berroco Aerial is the secondary yarn, requiring between 5 and 11 balls depending on size, in the color #3411 Tea Rose. Providence comes in 50-gram balls, while Aerial comes in 25-gram balls, allowing knitters to customize the visual effect by choosing complementary or contrasting colorways.

The needle requirements include 32-inch and 16-inch circular needles in both sizes 4 (3.5 mm) and 6 (4 mm), plus one set of double-pointed needles in each size for working small circumferences in the round. Additional notions include 8 stitch markers and a small amount of waste yarn for holding stitches during construction. Knitters should select needle sizes to obtain the specified gauge of 21 stitches and 28 rounds per 4 inches in Stockinette Stitch.
