With a few helpful hints, decorating for your blocks baby shower can be as easy as 1, 2, 3! You can find block-themed partyware or decorate tablecloths yourself with colored paper "blocks". Order matching block-themed baby gifts and use it as your centerpiece, or purchase alphabet blocks and stack them around the guest tables. The alphabet blocks can even be used for a game during the shower - have guests stack blocks as high as possible with their eyes closed or use the blocks to spell out baby name suggestions for the new mom!
By adding a little creativity to your menu planning, guests will be able to enjoy block-themed food at the shower. Cube up melons and serve them in a square dish. Cut sandwiches into squares and serve with cubes of cheese. You can even serve a block shaped cake by stacking 3 9x9 square cakes on top of one another, then frosting and decorating to look like a block. Finish with punch that has a giant ice "cube" rather than an ice ring, or add a little jiggle to your dessert with jello cubes. Who knew that hosting a block-themed baby shower would be so much fun!
