Weddings are just fun in general, but when you're engaged (or just a little wedding happy :P) they are goldmines for ideas!!!
A really great way to see how a wedding idea pans out is to see it in action, so when I do attend weddings, I'm also taking mental notes throughout the experience.
My bf knows me pretty well, the first wedding we attended he told me "Don't get any ideas." Although I think it was too late by then, tee hee :D
We will be going to one next week, and I'm really excited to see how this one turns out. They seem to be a more modern couple, and really have their ideas in mind, not just what the masses are doing these days.
I'll be sure to post what I liked and what worked in a couple weeks!
