Penguin in love is a cute little story about a pair of penguins who knit themselves into friendship. I think we may have used as much string as those penguins who knitted clothing for whales, seals and other arctic animals. The girls wrapped and wrapped their tiny little cardboard hearts with yards of string. Little scissor cuts along the edges helped to keep the string in place. If we ever do this type of art project again, I will definitely pick up some thicker weighted yarn!
