I read too many blogs, but for once it's actually coming in handy.
I found several blogs that did little boy's birthday parties with a "Little Man" theme, with mustaches and ties as decor ideas. Welll, I sorta stole that idea and ran with it.
Invites (The Etsy seller reworked them to say "A Little Man is On His Way!" and then put in the shower info.)
(Found a tutorial for these online, picked up the paint and mugs for cheap and I'm making them this week, filling with homemade cocoa mix and homemade marshmallows)
(I got aqua cupcake wrappers and some orange ribbon for these)
"Welcome Little Man" Banner like this:
And tie onesies! (Found a tutorial on a blog to make them and I got the stuff to make one in several sizes)
I made some water bottle wraps that are aqua and orange polka dots w/ a mustache printed on them, and we're serving "man food" (loaded baked potato bar w/ a lot of different toppings, Italian chopped salad)
Now I just have to put it all together and make everything!
