iParty does have Super Mario decorations, as does Party Express, but it is limited as to how much you can get. We got pretty crafty with this party, but were happy with the results. The first child that arrived loved it and said "it's like we are in a Mario game!" That made me smile!
Luckily we found some Martha Stewart 3x3 treat boxes on clearance at JoAnns. Some were covered as mystery boxes (created on MS Paint) and others covered with Brick Patterned paper from Hobby Lobby. These were great as stackable decorations and also for the hanging streamer in which I used silver star wire. Gold Coins are cardboard circles from the cake department at AC Moore, covered in gold Christmas wrap (after christmas clearance). Then used gold cardstock to make the 1 up on the coins. Other smalled gold coins we used as a banner with characters and foam stars. Pipes were made from green and lime green foam sheets wrapped around paper towel rolls. I glued and stapled them so they would stay. I then used free clipart on skewers to make Mario, Luigi and characters look like they were jumping out of the pipes.
I made the starry stars out of foam sheets adhered to chipboard/thin wooden stars, found at AC Moore. The flower was made from cardboard, felt, foam and covered paper towel roll. Super easy and it looks so cute and colorful. The green planters were found on clearance at AC Moore.
The phirana plant was a fun modge podge project! I covered a round balloon with modge podge, then red polka dot fabric. Next recovered it with another layer of modge podge and let dry. When dry, I cut out the shape from the sturdy fabric. Next I used a white felt and some creative glue gunning to make the mouth and teeth. The lime green planters had dividers in them to hold up the stem.
We played a few games... Pin the Mustache on Mario, indoor Yoshi Egg Hunt and Meatball Toss. The kids had a great time!!! The winner of the yoshi egg hunt won a t-shirt (mario of course). I hid two gold coins in one of the eggs, the rest had candy in them. I bought after christmas clearance gift bags for the prizes and then just deorated them with Super Mario Bros. characters. The pin the mustache game, I used a large printable picture of Mario. I used MS Paint to delete his mustache. I made a mustache template and just printed them out in different colors, one for each player. The Meatball Toss game was made from a free display from Toys R Us and some left over balls from the ball pit we had. I guess I could have filled it up with something that looked more like spaghetti, like yarn, but I forgot!
