You guys! A Sleep UNDER birthday party is GENIUS and ideal for kids who want to invite the whole class, which would be really unwieldy for a sleepover (not that the whole class could come, but still, we had 9 which is more than I would like to have for a sleepover.)
As soon as Jack got home from school, we ran to the Dollar Store (my new party planning mecca) for supplies and balloons-- he picked out giant fingers that said "You're #1!!" which was awesome.
We paired them with DQ gift cards-- easiest favors EVAR
And got right to work setting up the basement with a movie candy bonanza and bags of popcorn (the Dollar Store did not have cute popcorn bags-- I should have swung by Party City, but, alas. You know what they did have? 40 lunch bags for a DOLLAR! I freaking love the Dollar Store Also, you bet I took the tape off that $1 banner and put it away for our next party).
