Mini Jupiter Sweater Jumper Knitting Pattern

Mini Jupiter Sweater in MODE at Rowan Colourmix

What is Being Made

The Mini Jupiter is a children's pullover sweater designed by Quail Studio and available in five size options ranging from 3-4 years through 11-12 years. The sweater features a classic crew neckline and is constructed with set-in sleeves. Actual chest measurements range from 62.5 cm (24½ inches) for the smallest size to 86 cm (33½ inches) for the largest size, making this design suitable for growing children across multiple age ranges.

Knitting Techniques and Construction

This beginner-friendly sweater is constructed using fundamental knitting techniques appropriate for those new to garment construction. The pattern employs flat knitting on straight needles for the main body pieces, with a small circular needle reserved for the neckband finishing. The sweater is worked in separate pieces—back, front, and sleeves—which are then assembled together, a classic method that simplifies shaping and fitting for newer knitters.

Key shaping techniques used include M1L (make 1 left) and M1R (make 1 right) increases, which are worked by lifting the strand running between stitches and knitting through the back loop. These increases create nearly invisible new stitches, ideal for sleeve cap shaping and other fitted areas. The pattern also incorporates decreasing for sleeve shaping and uses cast off techniques to finish edges. The front neck features a shaped neckline with stitches held on stitch holders during construction, then worked separately for each shoulder to create a fitted crew neck opening.

Stitches and Stitch Patterns

The Mini Jupiter sweater uses two primary stitch patterns. The lower ribbed sections are worked in a K3, P2 rib pattern (knit 3 stitches, purl 2 stitches, repeating across the row), which creates an elastic, fitted cuff at the hem and sleeve openings. This ribbed section measures 8 cm in depth across all sizes, providing structure and recovery at the garment edges.

The main body and sleeves are worked in stockinette stitch (abbreviated as st st), which is created by alternating knit rows on the right side with purl rows on the wrong side. Stockinette stitch produces the smooth, classic sweater fabric with a V-shaped texture on the front and a bumpy texture on the reverse, making it ideal for a children's everyday garment. The tension for this pattern is set at 17 stitches and 24 rows to 10 cm measured over stockinette stitch, which is essential to achieve the correct finished measurements.

Materials: Yarn and Needles

The Mini Jupiter is designed to be knitted with MODE at Rowan Colourmix yarn, a worsted-weight yarn sold in 50-gram balls. Yarn requirements vary by size: the smallest size (3-4 years) requires 5 balls, increasing incrementally to 9 balls for the largest size (11-12 years). The pattern was photographed in two colorways: Rainbow 100 and Olive Greens 103, showcasing the versatility of the Colourmix range.

The pattern calls for 5mm (US size 8) needles for all main knitting. Specifically, one pair of straight 5mm needles is used for the back, front, and sleeves, while a 5mm circular needle measuring 40 cm is required for working the neckband in the round. This needle combination is straightforward and accessible for beginner knitters. Additional notions include stitch holders to temporarily hold stitches during neck shaping and stitch markers to help track pattern repeats and shaping points throughout construction.

Pattern Summary by Component

• Back Panel: Cast on 53–73 stitches depending on size. Work 8 cm in K3, P2 rib, then continue in stockinette stitch until the back measures 41–56 cm (depending on size), creating the full length of the garment from hem to shoulder.
• Front Panel: Worked identically to the back until reaching the neckline shaping point. The front neck is shaped by placing the center 13–17 stitches on a holder and working each shoulder separately with shaping to create a fitted crew neckline. Each shoulder continues until matching the back length, then stitches are cast off.
• Sleeves: Cast on 22–28 stitches (depending on size). Work 8
