The pattern for the 'foot' is:
Begin at feet with red:
Rnd 1: 8 sc in magic ring (8)
Rnd 2: sc in next sc, 2 sc in next sc around (12)
Rnd 3: sc in next 2 sc, 2 sc in next sc around (16)
Rnd 4: sc in next 3 sc, 2 sc in next sc around (20)
Rnd 5: sc in next 4 sc, 2 sc in next sc around (24)
Rnd 6-11: sc in each sc around (24)
Rnd 12: sc in each sc around, do not join round, ch 1 and turn (24)
Rnd 13-15: repeat rnd 12 (24)
Rnd 16: sc in next 10 sc, ch1 turn (10)
Rnd 17-19: repeat rnd 16 (10)
F/O. Leave long tail. Line up the edges of heel flap with opposite side of work (it will resemble a shoe shape'. Using tail and yarn needle, whipstitch the two sides to each other matching the stitches. Sew across the bottom of the 'heel'. Weave in ends.
After rounds 1-19, your 'foot' should like something like this:
Fold that flap over to meet the other side of the work (sort of like a door). Meet the two top edges together :
Using the tail you left and a tapestry needle, whipstitch the sides together (leave the opening at the 'top'.
Now there is a small 'opening' at the bottom of the heel (going across the bottom of the 'foot') Sew that closed as well, and secure and hide your ends.
You should then be left with something that looks like this:
And now you're ready to stuff the foot and proceed with the 'leg' portion of the pattern. You'll start by sc evenly around the opening you see there at the top to begin the leg.
Hope this helps you all, the pictures are a bit blurry (but I don't have a camera that really does the best closeup shots), but let me know if you have more questions!
