In the book I Wish That I Had Duck Feet by Dr. Seuss (as Theo LeSieg), the feet are orange.

Beginning is tricky (on dpns).
First tried on 3.0mm. Frogged.
Re-started with 2.5mm.

Changes:

• 2.5mm dpns
• Turkish Cast On
• center point shaping uses Turkish CO
• no purl stitches on sole
• M1L instead of LLI; M1R instead of RLI
• Heel: work first 9 sts …
• row 13: knit to center stitch
• 2-st i-cord BO up CB
• 2-st i-cord along instep (3-st would be better) but not on sole
• 2-st i-cord from tip of L toe, around back to tip of R toe
• 32-st cuff: 20 rounds in K1, P1.

If the centre stitches on the sole are purled, and then an i-cord is done along that, the bootie can be done with 2 fewer ends to darn in. But the knitting will take longer.
