All I can say is how freaking adorable is this monster party? It was sent to me by Katherine of the blog The Side Stuff. She threw it as a Friday the 13th playdate for her own children and some other moms and their munchkins. Because she doesn't do a lot of playdates, Katherine decided to go all out. She looked to Pinterest for some perfect rainy date activities, which included making old fashioned cereal necklaces,squishy paint bags on the windows, and velcro popsicle sticks. We have lots more photos after the jump. And for more details on the party, be sure to visit Katherine's original post.
