reader question of the week #2

reader question of the week #2:

"My twin boys turn one in June and I'm trying to come up with something a little different for their party. I want a theme that makes note of the fact that they are twins (all too soon they'll be deciding the theme for themselves and probably won't care about their awesome twin-ness), but it doesn't necessarily have to be the whole entire theme.The party will be in an open-air pavilion in a local park. I'm leaning towards something old-fashioned, evoking a sort of classic Christopher Robin-era feel (but without actually doing anything Winnie the Pooh!). Any ideas would be much appreciated! Thanks! -Rachel"
