If you're looking for something unique for the nursery- this alphabet poster might do the trick. Each letter of this alphabet poster was discovered in nature, on the wing of a real butterfly.
It all began when future husband and wife team, Barbara Bedette and Kjell Sandved, were working together at the Smithsonian and they discovered an old cigar box with a butterfly wing with the letter F on it. Barbara thought, "If Nature can create one such perfect letter, there must be others flying around out there. Let's go out and find more." And so began their journey around the world.
You'll find the Alphabet Poster, as well as this Nature Poster- with images from throughout nature, on the Butterfly Alphabet Inc. website.
Another original nursery idea- how about spelling out the name of your child in butterfly letters? The first of these butterfly names was actually presented to Queen Elizabeth herself. Each 3.5" x 5" Kodak letters is $2.50.
If you're looking for an afternoon activity, check out the website with your kids. Explore the gallery of "Funny Faces" that have all been discovered in nature. For example, look closely at the Pleurothallis Orchid from Venezuela above. Remind you of anything? It's available at the site as an 8 x 10 or 11 x 14 Kodak nonfading photograph, and it's title..."The Screaming Baby".
