craftgrrl | Keep hair-flower from wilting....

Hi Everyone,

I went through the memories section to see if I could find an answer to the following question, but nothing quite addressed this, hopefully someone can help.

I'll be attending a wedding next weekend and want to wear a real flower in my hair (actually tucked behind my ear -- a lily or hibiscus or something along those lines) I've tried wearing flowers in my hair before and they always seem to wilt after a couple of hours- I need this flower to hold up for the better part of the evening. I was trying to think of things that might work to keep the flower perky through the reception and all I could come up with was maybe spraying the flower with hairspray (no idea if this would work, just the first ting that came to mind). Does anyone know of a way to keep a fresh flower from wilting once it's out of water?
Thanks in advance for any help anyone can give.
Have a great night!!
