My absolute FAVORITE thing to do is plan and prepare for parties. I swear, if I were rich I'd host a party each month JUST for the planning part. Pinterest has been awesome for planning for Sadie's third birthday. The theme? Mermaids! Look at all I've posted so far!

One site gave me the idea of including scuba divers, too. This works perfectly since there are several boys attending. The very first few Pinterest ideas that I've been working on (with the help of my Mom- Ms. Pinterest herself) are for the invitation and a party favor.
The invitation is a compilation of several pins. Sarah B gave me the idea to do a message-in-a-bottle invite, which I love! We worked on the wording and my mom worked her magic. As a result, we came up with this as the invitation.
Supplies:

Message:
Dive deep into the ocean blue,with mermaids and scuba divers, too.Here we will celebrate under the sea,as Miss Sadie is turning three!Insert (plus crushed shells, pearls, & tiny seahorses):
*Instagram effect makes this appear more vintage than it actually is.Finished product (kind-of):

I'll mail each family a plastic message in a bottle with the invitation. I hope the kids get excited about Sadie's upcoming birthday party!
Next, I saw this pin and fell in love.

It's not near as a easy as it looked, though! I followed the directions
here, but found that it took a TON of time. Not sure anyone besides Sadie will be wearing a koi fish in their hair! :-)

SOOOO much to do before her party. It's going to be the best one yet!
