Not many people know this, but you can take your kiddos to you local Lowe's or Home Depot for monthly workshops and some of them will actually do birthday parties. We had a birthday party at Lowe's this year and it was a hit!
The kids all received an apron to wear, hammer, goggles and a kit of their choice with all of the items and instructions inside to build it. And best of all, it was all free!
Invitation was created in Photoshop and printed out on cardstock to mail.
My boys aren't big fans of cake, so we came up with a few alternatives. The cake bites were a new thing I had tried to make (I'll post something on them later). Basically cake, covered in chocolate and on a stick. The toolbox was something my husband whipped out with some scrap pieces of wood and I painted it with some old red paint from the garage. It's filled with some brownie bites that I just picked up from the local grocery store (Albertsons bakery).



For party favors, I bought these packages of Crayola paint pens for the kids to take home and paint their wooden project they had just made.

Update: Added a few more pics of the party....
