Backyard Construction Truck Birthday

I recently discovered Mr. McGroovy's Box Rivets, which is this wonderful site that sells rivets and building plans for elaborate cardboard box creations - from princess castles to pirate ships.  They are surprisingly easy to build (according to the friends that built one), look amazing, and kids LOVE them.

I'm already thinking what I could do for my kids for their birthdays this year.  My son loves all things cars and trucks, so here's my list of what I might do if I have time:

1.  Make some Cardboard Construction Trucks from Mr. McGroovy's Box Rivets.

2.  Make some Traffic Light Treat Bags.

3.  Buy some Construction Sign Cutouts and Caution Party Tape.

4.  If my son were younger, I would certainly go for the Traffic Cone Party Hats, which are just too cute.  But he'll be five and wouldn't wear them.  So I think I'll go for Construction Hats instead.

5.  I'll get one of those great road cupcake cakes from Publix and top it off with some toy construction vehicles and these super cute Traffic Cone Candles.

6.  Then all I need are some Construction Themed Paper Plates, plain napkins, and a lot of balloons.

Thanks to the Cardboard Construction Trucks, I don't even need to plan a lot of entertainment, just let them play and have a great time.  Now, for the bigger question - how many grocery stores do I have to canvas for used cardboard boxes?
