Making a wand
One of the most common mistakes in making a wand is to make it too long. For example, Harry Potter's original wand was only 11 inches long. (For safety purposes, keep this in mind. Do you really want a bunch of 7 year olds running around in the dark with long sticks?)
Traditional wands were made of wood. A wooden dowel can be shortened to the right length and stained or painted the preferred color. Wands can also be made out of ivory, or the modern versions, plastic. If you don't want to make your own, there are commercial sites where you can buy a wand.
