I love this fabric too. Something about polka dots make me so happy! This came from my foraging through my cousin's stash on my trip down to LA. The block was freezer paper pieced.
This block makes me think of the Paul Revere poem. "One if by land, two if by sea..." I used to have the whole thing memorized, but now I can only remember one or two lines. I remember being VERY excited when we went to Boston and walked the Liberty Trail and we walked by the bell tower where the lanterns were hung. History is so fascinating!!
