The Shell Stitch Tee is a free, intermediate-level crochet pattern designed by Paintbox Yarns for women's tops. This cheerful, lightweight pullover tee is worked in bold horizontal stripes using a classic shell stitch construction, combining both flat and in-the-round crochet techniques to create a finished garment with a relaxed, summery feel. The pattern is available as a downloadable PDF and is written in US terminology with UK equivalents provided throughout.

What Is Being Made

This pattern produces a women's crocheted tee-style pullover sweater. The design features a striped colorwork layout worked in multiple colors of Paintbox Yarns Cotton DK, creating a vibrant, eye-catching finished garment. The shell stitch detailing gives the fabric a lacy, open texture that makes it ideal for warmer seasons. The tee is available in a range of sizes, accommodating a wide variety of body measurements, with instructions clearly written for the smallest size and larger sizes given in parentheses throughout.

Techniques Used

• Bottom-up construction: The tee is worked from the lower hem upward, a traditional approach that allows for easy length adjustments as you go.
• Worked flat: Sections of the garment are crocheted back and forth in rows, producing a fabric that is later seamed together for a neat, structured finish.
• Worked in the round: Certain portions of the construction are crocheted in continuous or joined rounds, reducing the number of seams needed and creating a smooth, seamless tube where applicable.
• Seamed construction: The finished pieces are joined together using seaming, a technique common in garment making that adds durability and shape to the final top.
• Stripes: Horizontal color stripes are a central design feature, requiring yarn color changes at regular intervals. Carrying or cutting yarn between stripes is a key skill practiced in this pattern.
• Lace: The shell stitch itself creates an open, lace-like fabric. Shell stitches are formed by working multiple double crochet stitches (US) — known as treble crochet in UK terminology — into a single stitch or space, fanning out to create a shell or fan shape. This technique adds visual texture and a delicate, airy quality to the fabric.

Stitches Used

The shell stitch is the signature stitch of this pattern and forms the main body fabric. In crochet, a shell stitch is created by working a group of double crochet stitches (treble crochet in UK terms) into the same stitch or chain space, producing a fan-shaped cluster that repeats across each row or round. This stitch is well-suited to DK weight cotton yarn, as the fiber's smooth texture and stitch definition allow the shell shapes to stand out clearly. Additional foundational stitches such as chain stitches and slip stitches are used throughout for turning, joining rounds, and finishing edges.

Materials – Yarn and Fiber

The pattern calls for Paintbox Yarns Cotton DK, a 100% cotton yarn sold in 1¾oz / 50g balls. Cotton DK is a popular choice for warm-weather garments due to its breathability, stitch definition, and washability. The pattern uses four colors in a striped arrangement:

• Paper White (Color A) – the primary color, requiring the most balls across all sizes: 3(4:5:6:6:7:8) balls
• Mustard Yellow (Color B) – 2(3:3:3:4:4:5) balls
• Bubblegum Pink (Color C) – 2(2:3:3:4:4:5) balls
• Dusty Lilac (Color D) – 2(2:3:4:4:5:5) balls

The total yarn requirement varies by size, so it is important to select the correct quantities for your chosen size before beginning. As noted by Paintbox Yarns, yarn quantities are based on average requirements and are therefore approximate.
