A Real CORN COB PATTERN! (see below for a less professional option)

Corn Cob Pattern
Start by holdings two strands of "Loop and Thread" Chrisma Yellow (for added dimension add a third strand in fingering weight in the yellow color scheme)

Cast on 23 stitches on size 13 needles holding the 2-3 strands together.
Knit every row (garter stitch) until piece measures 18 inches.
Decreases- knit the first two stitches together, then the following two stitches. Knit...

straight across until 4 stitches remain. Knit two together twice. Knit the following row straight. Repeat decrease row twice and bind off.
Then sew from the bottom up, leaving the fat end off the cob open for stuffing. Pull the top of the ear tight to create a pointed tip. Stuff with poly fill. Sew the bottom shut.

Husk-- I just covered my cob in a large sheet of green Eco-felt and hot glued it to the cob. Then cut in leaf shapes and added a tassel/silk.
