I've never participated in a blog party before, but I thought I'd give it a try. Vanessa of A Fanciful Twist hosts a Halloween party, and it looks like fun. Her blog is the very embodiment of "fanciful" and she seems like a whirling dervish of whimsical creativity.
Halloween was always my favorite holiday (I looove an excuse to put on a costume - yeah, I'm a geek that way). The past few years have been sorely lacking in Halloween-y type celebrations so I'm looking forward to this online masquerade. If you would like to participate, here is the link with instructions, etc.
