I'm sorry but I just have to get this out there. It has been on my mind since this polka dot swap started. I hummed it while I cut and sorted all my charms this month:
"....she wore an itsy bitsy teeny weeny yellow polka dot bikini....that she wore for the first time today....."
And that is the only possible cultural reference I can come up with for polka dots! No other songs, book titles or movies!
Thanks for letting me get that off my mind.
