The number one place to buy cute stuff is hosting a "Week of Cute" with Angela from Sew Your Own.
I'm all about having a crack & so I'm playing along. These cards are Rootie Kazootie. I bought them without knowing anything about the TV show (from the 1950s). The kids & I were on our hands & knees sifting through a HUGE box of cards. Rootie Kazootie cards were the needle in the haystack. I think we were there for about an hour.
I'm particularly partial to Polka Dottie. I think that she is super cute.
