Collies, as I've mentioned before, possess a natural stick magnetism, and are especially helpful at collecting sticks. This skill comes in handy when you're making a witch, because a stick makes a very handy thing on which to stick a witch.
In fact, sticks make great frames for all sorts of haunt critters. If you don't have a readily available supply of witch sticks in your yard, then a tomato stake, or any sturdy piece of wood will do the trick. The longer the stick, the taller the witch. I chose a length of about 5'.
A spare Christmas tree stand not only makes a great stick holder during construction, but also does an outstanding job of displaying your witch.
Sheepdogs, celebrated companions though they are, subscribe to a work ethic altogether different from that of the collie. Sticks are not as attracted by, nor attractive to, a sheepdog, making her stick gathering ability in need of a saving throw*. However, she excels at cat herding, and is a superior accumulator of rubber balls.
