We've been trying to make happy, springy things to hang up around the boat... hoping we can lure the buds from the branches and the flowers from the soil around the marina.
This is about as easy as they come for a kid craft. Coffee filter butterflies (can't remember where I saw this idea... either a book or blog...) Take a coffee filter and open it up at the seam (we had to steal some from friends as we don't drink coffee). Paint all sorts of happy colors. Bend a pipe cleaner (ok, chenile stem if you must) in half on the middle of the filter and twist at the top. This becomes the butterfly body and antennae. Hang it up and voila - instant spring time happiness!
