Materials Needed

Before you begin, gather the following supplies. Having everything ready will make your crochet session smooth and enjoyable.

Yarn

• Worsted weight yarn in 3 colors:
  • Main Color (MC): Soft Cream – Approximately 600 (700, 800) yards for sizes S/M (L/XL, 2XL/3XL)
  • Contrast Color 1 (CC1): Dusty Rose – Approximately 300 (350, 400) yards
  • Contrast Color 2 (CC2): Sage Green – Approximately 300 (350, 400) yards

Hook & Notions

• 5.5 mm (I-9) crochet hook, or size needed to obtain gauge
• Stitch markers
• Tapestry needle for weaving in ends
• Scissors

Gauge

16 stitches x 18 rows = 4 inches in mosaic single crochet pattern (worked flat). Always check your gauge to ensure your sweater fits as intended. If your gauge is off, adjust your hook size accordingly.

Step-by-Step Instructions

This pattern is worked in flat panels (back, front, and two sleeves) and then seamed together. The mosaic pattern is created by working elongated stitches into rows below, alternating colors every two rows. Don't worry – it's easier than it sounds! Follow along carefully, and you'll have a beautiful sweater in no time.

Sizes & Finished Measurements

• S/M: Finished bust 36 inches, length 18 inches
• L/XL: Finished bust 42 inches, length 19 inches
• 2XL/3XL: Finished bust 48 inches, length 20 inches

Special Stitches

• Mosaic Single Crochet (msc): Insert hook into front loop only of the stitch two rows below, yarn over, pull up a loop, yarn over, pull through both loops on hook. This creates a long, elongated stitch that forms the mosaic pattern.
• Single Crochet (sc): Standard single crochet: insert hook, yarn over, pull up a loop, yarn over, pull through both loops.
• Chain (ch): Standard chain stitch.

Pattern Notes

• The sweater is worked in panels: back, front, and two sleeves, then seamed together.
• The mosaic pattern is worked in rows, alternating colors every two rows. Always work with the right side facing for the mosaic rows; wrong side rows are worked in sc with the same color.
• Carry the unused color loosely along the side edge, or cut and rejoin as preferred. For a cleaner finish, many crocheters prefer to cut and rejoin at each color change.
