Check it out down below, I figured out how to add a cute signature!
The font is Pea Nicki from the Fonts for Peas section of one of my favorite blogs, kevinandamanda.com. She'll turn your handwriting into a font for free!! If I liked my handwriting I'd totally do it, but I don't so Nicki's will have to do. Thank you Nicki, whoever (whomever?) and wherever you are :P
Edited 1/16/11: I'm playing around with my blog layout and can't get the cool signature to automatically post so I'm just adding the link/code at the end of every post I make. Kind of a pain, but now it will show up after my writing instead of farther down after the LinkWithin widget like it was before.
I also realized I didn't post where/how I learned to do it, so you can find directions on the awesome Keving & Amanda blog here.
