Here is a simple handwritten font that is great for Halloween. I love to use this font for my Halloween banners because it is easy and you don't need any special drawing ability. The messier your penmanship is the better. I sometimes even write the words with my left (I'm a rightly) hand just to get the lines messier. There is a video tutorial below will show you how to create this font. All you have to do is write the words with a broad marker (Crayola Markers, Highlighters, or even these cheapie Sponge Bob party favor markers work).
Draw out the word with marker. The messier the better.
Outline the marker with a black ink pen (not ball point).

This also looks pretty cool with yellow highlighter also.
