Willow & Lark Henrietta Frill Jumper Knitting Pattern

Willow & Lark Henrietta Frill Jumper

What Is Being Made

The Henrietta Frill Jumper is a knitted sweater designed by Willow & Lark as part of their Chintz Collection. This intermediate-level pullover features a distinctive frill detail and is available in five sizes to fit bust measurements from 81–127 cm (32–50 inches). The finished garment offers a comfortable fit with actual underarm measurements ranging from 95 to 139 cm, and finished lengths between 60 and 64 cm, making it suitable for a range of body types and style preferences.

Techniques Used

The Henrietta Frill Jumper is constructed using a bottom-up method, meaning the body and sleeves are knitted beginning at the lower edge and working upward toward the shoulders. The garment is worked flat on straight needles rather than in the round, and pieces are seamed together once individual components are complete. This construction approach is typical of classic sweater design and allows for precise shaping and frill placement throughout the garment.

Stitches and Stitch Patterns

The primary stitch used in this jumper is stocking stitch (also called stockinette stitch), which creates a smooth, classic fabric with a flat appearance on the right side. Stocking stitch is achieved by alternating knit and purl rows in a regular pattern. The pattern instructions include standard knitting abbreviations such as K (knit), P (purl), inc (increase), dec (decrease), and rep (repeat), which guide shaping and texture variations throughout the design. The frill detail that gives this jumper its distinctive character is created through increases and decreases worked into the stocking stitch base.

Materials and Tools

The recommended yarn for the Henrietta Frill Jumper is Willow & Lark Ramble, a 100% wool yarn in DK weight. Each ball contains 50g (1¾ oz) of yarn. The color specified in the pattern is Limestone, and yarn requirements range from 10 to 12 balls depending on the size being knitted. Knitting needles required include a pair of 4.00mm (UK 8 / US 6) straight needles for working the flat pieces and a 4.00mm (UK 8 / US 6) circular needle or set of four double-pointed needles for any ribbed or in-the-round sections such as necklines or cuffs.

Tension and Sizing

Correct tension is essential for this project to fit as intended. The pattern specifies a tension of 22 stitches and 30 rows to 10 cm (4 inches) measured over stocking stitch using 4.00mm needles. Knitters are strongly advised to knit a tension swatch at least 12 cm (5 inches) square before beginning the garment. If your swatch contains more stitches and rows than specified, use thicker needles; if it contains fewer, use thinner needles. The pattern is written with instructions for the smallest size, with adjustments provided for larger sizes throughout.

Design Notes

The Henrietta Frill Jumper is classified as an intermediate difficulty project, suitable for knitters with foundational skills in shaping, seaming, and following multi-size patterns. The design emphasizes the natural drape and warmth of pure wool, making it a versatile layering piece. Sleeve length remains consistent at approximately 45–47 cm across all sizes, while finished length increases slightly with larger sizes to maintain proportional fit.
