3.5mm hook for smaller dolls

Larger version can be made using the same pattern and doubling up the yarn with a 4.5mm hook.

This pattern is versatile and can be sized up or down depending on your yarn size. Any yarn will work provided you use an appropriate hook (i.e. one slightly smaller than recommended for a tight weave).
Small dolls measure ~5-6 inches tall, large doll measured ~8-9 inches.
