From pattern page:

This little guy works up in a few hours and makes a great handmade gift for crafty people.

Materials:

• Round tape measure, a little over 2” (over 5cm) in diameter and about ½“ (1.25cm) high, with the retracting button in the middle of one side. I used Knit Picks’ brand, but I believe Singer makes a nearly identical model.
• DK weight yarn, approximately 25yd (22m) for shell and 12yd (11m) for body. I used Tahki Cotton Classic.
• Size E hook (3.5mm) or hook required for gauge.
• Small amount of fiberfill
• 2 6mm safety eyes (optional)
• Very small amount of red yarn or embroidery floss for mouth
• White craft glue
• Small amount of thin fabric (optional but recommended)
