I adapted the knit a circle instructions here to make the white disks for the eyes. This is a bit fiddly. The first gopher I did had crocheted eyes that my wife made for me. I wanted to make an “all knit” pattern, so I worked this out, but if you know how to crochet (or if you have a crocheter in the house like I do!), consider doing that instead.
CO 1
Row 1: k1, p1, k1 in the same stitch. (3 sts)
Row 2: Turn the needle and purl across the row.
Row 3: Turn the needle again, kfb all stitches. (6 sts)
Row 4: Divide onto three DPNs, join, and knit around.
Row 5: Kfb all stitches. (12 sts)
Row 6: Knit around.
Row 7: [Kfb, K1] around. (18 sts)
Bind off, leaving a long tail.
Place 9 mm black plastic eyes in centers. Position eyes on body and sew in place with the tail from binding off.
