Part 2: Sewing the Foot Together
Step 1: Sew together the cast-on edge, then part-way up the back seam.
Step 2: Add a small amount of stuffing to the leg. There should be no stuffing in the foot. Finish sewing the back seam, and weave in this yarn end.
Step 3: Flatten the foot, so the leg is towards the back, and the foot is symmetrical. Use a safety pin to hold the two layers of the foot together.
Step 4: Cut a 25 cm (10") length of yarn the same colour as the foot and thread it onto your needle (I'm using a contrasting colour so you can see my stitches). Insert the needle at the center-bottom of the foot, and exit to one side of the center-top of the foot. Leave about 7 cm (3") of yarn where you started.
Step 5: Using a running-stitch, make 2 short stitches towards the edge of the foot, following a column of stitches to keep your line straight. End on the underside of the foot.
Step 6: Make a stitch around the edge of the foot, then work back towards the center of the foot, making a stitch between your first 2 stitches. Exit on the other side of the center-top.
Step 7: Stitch a line on the other side of the foot, just like the first.
Step 8: Thread your yarn to where you began, and knot your yarn ends together. Weave the ends through the foot 2-3 times, pulling on the knot so it slips inside the foot. Your yarn ends should now be secure.
Here is the finished foot, with the stitching done in the correct colour. You can see that it's nearly invisible, and the foot now has the right shape. Maybe they're a bit rounder than real duck feet, but perfectly cute for a silly toy duck!
