A few of those bows have been sitting on the windowsill of my office since then. The window has western exposure in the pacific northwest, and the view out the window is solid woods. This means I don't have a real high level of sun exposure --at least not for many days of the year. I was cleaning and organizing today, and noticed the bows and... (Really? It's been that long that they've been just sitting there?) and...OH MY GOSH!!! I couldn't believe the colors or should I say lack of!
Can you see how the right half of the bow is almost bleached to white?
Check this out! See that bit of orange "shadow"?
Here is the bottom side of the bow which is pretty much the original colors:
So in summary: The sun is a very strong bleach agent. Protect photographs and other precious memorabilia from direct sun. A scrapbook does an excellent job of this, as does a certain expensive type of framing glass. Even your fabric furniture will fade if exposed to direct sun, so use your blinds, curtains, or shades. Wear sunglasses to protect your eyes, and of course, apply sunscreen to your skin. Even in the Pacific Northwest:)
