Whether you’re curling up with a good book or adding a cozy layer to your living room decor, this afghan is a rewarding project that yields an heirloom-quality piece. Let’s get started!

Materials Needed

Before you begin, gather the following supplies. Using the exact yarn and hook size will ensure your afghan matches the intended size and texture.

• Yarn: Red Heart Super Saver (100% acrylic, 7 oz/198 g, 364 yds/333 m) in 4 colors:
  • Color A - Pumpkin (approx. 3 skeins)
  • Color B - Buff (approx. 2 skeins)
  • Color C - Claret (approx. 2 skeins)
  • Color D - Coffee (approx. 2 skeins)
• Hook: Crochet hook size J-10 (6.0 mm) or size needed to obtain gauge
• Other: Yarn needle for weaving in ends, scissors

Gauge

14 stitches and 8 rows in mosaic pattern = 4 inches (10 cm). To check gauge, work a 4x4 inch swatch in the mosaic pattern (Rows 2-3 of the pattern below). Adjust your hook size if necessary to match this gauge.
