Materials: Yarn, Needles, and Notions

Yarn

The pattern calls for Tahki Yarns Cotton Classic, a 100% mercerized cotton yarn in a DK weight. Each skein contains 1.75 oz / 50g and approximately 108 yards / 100m. The sample shown in the pattern is worked in color #3928 light lavender, a soft and fresh tone ideal for a summer or spring tank. Yardage requirements by size are as follows:

• X-Small and Small: 6 skeins
• Medium: 7 skeins
• Large: 8 skeins
• XL and 2X: 9 skeins
• 3X: 10 skeins

Mercerized cotton is an excellent choice for a tank top — it has a subtle sheen, holds stitch definition beautifully (making it ideal for showcasing cables), and is breathable and comfortable against the skin in warm weather.

Needles and Notions

• US size 7 (4.5mm) straight or single-point needles for the main body pieces
• US size 7 (4.5mm) circular needle, 16"/40cm long for finishing the armhole edges
• US size 7 (4.5mm) circular needle, 24"/60cm long for the neckband
• Cable needle for working the cable pattern stitches
• Stitch markers to mark pattern sections
• Small stitch holder or safety pin for holding live stitches
• Yarn needle for seaming and finishing

Gauge

The pattern gauge is 19 stitches and 26 rows = 4 inches / 10 cm in Stockinette stitch using US size 7 (4.5mm) needles. As always with garment knitting, achieving correct gauge is essential to ensure the finished tank matches the intended measurements. Knitters are advised to swatch and adjust needle size as needed before beginning.

Construction and Techniques

The Castle Rock Tank is worked flat in separate pieces — a traditional seamed construction — meaning the front and back are knitted individually and then joined together. This method gives the finished garment clean, stable seams and a structured fit. The seamed construction also makes it easier for intermediate knitters to manage the shaping and cable panels section by section.
