Lately, I'm seeing a lot of boxes of fake fall foliage in stores. This got me to thinking....if people would actually buy a box of fake leaves, how thrilled would they be to receive a box of real leaves? If you live where the leaves change, fill a gift box with fall leaves. Tie a big velvet bow around it in a fall color. You could also choose acorns or even pine cones. Send them to someone who doesn't live where they get to experience this bit of nature. Write a simple note saying you wanted them to experience the season. Besides for shipping, you have a thoughtful gift that didn't cost anything. If you want to take it up a notch, put them in a glass container. Nature does provide the best gifts.....actually, you could write something like that on the tag......."wanted you to experience the gifts of nature".
P.S. If you choose acorns, freeze them first to make sure they aren't home to any little beasties.
