Materials Needed

Before you begin, gather the following supplies. Using the exact yarn weight and needle size will ensure your slippers fit perfectly and have the right drape.

• Yarn: Worsted weight (#4) yarn in 3 colors. You’ll need approximately 100g total.

  • Color B: Midnight Blue (approx. 30g)

• Gauge: 18 stitches x 24 rows = 4 inches in stockinette stitch. Always check your gauge for best results.
