Mine were quite small, 4" x 2.25", as I wanted them to be toys that could go in a childs pocket. To make, decide what finished size you want, draw on a piece of paper drawing in legs, arms where colours change etc, then double the width. Cut out the shape, do a small tension square if you need to then knit up to match your paper pattern draw wool through stitches at top of head, pull tight then sew down back seam. Stuff and sew across bottom to close. Stitch through all layers tightly to form legs and arms, draw a length of wool through at neck following your drawing, sew on face and hair, step back and admire your work.
I find drawing up an actual size paper pattern is an easy way to design and knit your own items.
