Berroco Jumper Knitting Pattern

Berroco Mitridae Knit Sweater

What Is Being Made

The Mitridae is an intermediate-level knit sweater designed by Mel Kennelly. This pullover garment features a fitted silhouette with finished bust measurements ranging from 36 inches to 72 inches (91.5 cm to 183 cm), accommodating multiple size options. The sweater length varies from approximately 22¾ inches to 28¾ inches (58 cm to 73 cm) depending on size selection. The pattern is designed with 4–6 inches (10–15 cm) of positive ease for a comfortable, wearable fit.

Construction Techniques

The Mitridae sweater employs a bottom-up construction method worked primarily in the round using circular needles. The body is knit as one continuous piece from the lower edge upward until the underarms, where the work is divided to accommodate shaping. The back and front panels are then worked flat in rows and seamed together at the shoulders, creating a structured garment with defined armhole shaping. Sleeves are incorporated using double-pointed needles or preferred needles for working small circumferences, allowing for seamless construction in the round at the sleeve cap.

Stitches and Stitch Techniques

The primary stitch pattern used throughout the Mitridae is stockinette stitch (St st), which creates a smooth, classic fabric with a flat appearance on the right side and bumpy texture on the wrong side. This foundational stitch is worked consistently across the body and sleeves, providing an ideal canvas for the sweater's tailored silhouette. The pattern incorporates armhole shaping and sleeve cap construction, requiring knitters to increase and decrease stitches strategically to achieve proper fit and garment structure.

Materials: Yarn and Needles

Yarn: The Mitridae pattern calls for Berroco Bozzolo yarn, a premium fiber option available in two colorways. Saddleback (color #10806) serves as the primary color (C1), requiring 3–6 balls depending on size, with each ball weighing 100 grams. Sagebrush (color #10830) is used as a secondary color (C2), requiring 3–4 balls across all sizes. The two-color combination creates visual interest and allows for creative colorwork possibilities within the sweater design.

Needles: Knitters will need circular needles in two sizes: US 8 / 5 mm and US 6 / 4 mm, with both 16-inch (40 cm) and 32-inch (80 cm) lengths to accommodate different construction stages. Double-pointed needles in matching sizes (US 8 / 5 mm and US 6 / 4 mm) are required for working small circumferences, particularly for sleeve caps and finishing. The pattern recommends selecting needle size to achieve the specified gauge of 16 stitches and 25 rows/rounds per 4 inches (10 cm) in stockinette stitch using the larger needle size, measured after blocking.

Additional Notions and Finishing

The pattern requires two stitch markers for tracking increases, decreases, and pattern repeats during construction. Waste yarn is needed to hold stitches temporarily during the transition from circular to flat knitting and for seaming the back and front panels together at the shoulders. Proper gauge measurement after blocking is emphasized as essential for ensuring accurate finished measurements and proper fit.
