My oldest daughter (she's 3) helped me make some paper chain decorations, which I used to dress up door frames and the staircase in our foyer. These are a super easy alternative to streamers, which we also used to decorate and add another layer of texture to decorations as well as are a great project for me to tackle with my daughter. She loved making them so much that we made an extra one (in pink of course) to decorate her bedroom! I purchased the paper to match out theme at Michaels Arts and Crafts, and it was on sale 2/$1.00, so for about $4.50 I made two blue and yellow chains and one pink one. For these chains I used my paper cutter to cut 1 inch strips and used tape to attach them, this was also a great pattern exercise for my daughter since she picked each strip in order to add to the chain and keep the pattern consistent.
Along with our cake I also made double fudge cupcakes and topped them with Wilton's Extra Special Buttercream Frosting (http://www.wilton.com/recipe/Extra-Special-Buttercream-Icing-1) The frosting was delicious, but before you make this ahead please note that it must stay refridgerated until just before serving.
