Are you having a Halloween Monster Mash at your place this year? Then start scaring up your Halloween-theme decorations. And don't forget the invitations. Dripping Blood fonts are especially popular around Halloween (gee, I wonder why).
But when you're designing your Halloween invites and posters, try to use the dripping fonts at larger sizes and for small amounts of text. They aren't easy to read in small sizes and they loose their effect if every word is dripping blood. Here's an assortment of free Halloween fonts, including spooky dingbats.
A reminder also, digital fonts don't come in colors. If you want blood red letters you'll need to color them red in your software. For a font that is solid, just setting the color to red works. For hollow fonts that you want to have in color, you'll need fill in the letters in a graphics program. See "Why are my fonts not in color?" for more info.
