Here's what we've been enjoying on our living room window the past couple days:
They only last a few days, but they're so fun to make and so pretty! I taped a piece of clear contact paper to the window, sticky side out. Then my son carefully placed flower petals and leaves on it that we had collected from outside: impatiens from the balcony, a sort of purple flower from a bush, some pretty little buttercups from a walk we took earlier in the day, and some rose petals from a bouquet. Then we put a matching piece of contact paper on top to seal it.
