Seaside Sweater: Free Crochet Jumper Pattern for Women by Paintbox Yarns

The Seaside Sweater is a beautifully crafted women's crochet jumper designed by Paintbox Yarns, available as a free downloadable PDF pattern. Combining a relaxed, wearable silhouette with elegant lace detailing, this intermediate-level design is an excellent project for crocheters who are comfortable with the basics and ready to explore more refined construction techniques. The pattern is sized inclusively, covering chest measurements from 32–34 in (81–86 cm) up to 56–58 in (142–147 cm), making it a versatile make for a wide range of body types.

Finished Measurements and Sizing

The Seaside Sweater is offered in seven sizes, with finished chest measurements ranging from 38½ in (98 cm) to 62¼ in (158 cm), providing a comfortable, relaxed ease across all sizes. The finished length ranges from 20¾ in (53 cm) to 23¼ in (59 cm), and sleeve lengths range from 12½ in (32 cm) to 14¼ in (45 cm) depending on size. These generous dimensions give the sweater a laid-back, coastal feel that suits its name perfectly.

What Is Being Made

The Seaside Sweater is a women's pullover jumper — a garment worn over the head with no front opening — featuring sleeves and a structured body. The design has a summery, relaxed aesthetic that is well-suited to warmer months or layering in cooler weather. Its lace elements add a delicate, airy quality that complements the breathable nature of the yarn used.

Techniques and Construction

This pattern uses a combination of three key construction approaches:

• Lace crochet: Lace detailing is incorporated into the fabric, creating an open, decorative texture. Lace in crochet typically involves strategic use of chain spaces and stitch combinations to form repeating motifs or mesh-like sections. In the Seaside Sweater, this technique contributes to the garment's light, coastal character.
• Worked flat: The pieces of this sweater are crocheted flat — meaning they are worked back and forth in rows rather than in the round. This is a traditional construction method that gives the crocheter precise control over shaping and stitch placement, and is particularly well-suited to structured garments like sweaters.
• Seamed construction: Once the individual pieces are completed, they are joined together using seaming. This technique is common in garment making and results in a polished, tailored finish. Seamed garments often have greater structural integrity and a cleaner drape compared to seamless alternatives.

Stitches Used

The Seaside Sweater pattern uses a selection of standard crochet stitches, referenced in both US and UK terminology throughout the pattern:

• Double crochet (US) / Treble crochet (UK) — dc/tr: A tall, versatile stitch that forms the backbone of many crochet fabric structures. It creates a slightly open, flexible fabric ideal for garments.
• Single crochet (US) / Double crochet (UK) — sc/dc: A short, dense stitch often used for edgings, shaping, and finishing details. It provides structure and neatness at seams and borders.
• Chain (ch): The foundational stitch of crochet, used to begin rows and to create the open spaces characteristic of lace patterns.
• Slip stitch (ss): A very short stitch used for joining, moving across stitches without adding height, and finishing edges cleanly.

The overall stitch pattern is worked to a gauge of 20 stitches and 10 rows over 4 in (10 cm), which is essential to achieve the correct finished dimensions. Achieving accurate gauge before beginning is strongly recommended, particularly for a fitted garment like a sweater.
