Here's a pic of the tree on our campus at work that bares the beautiful acorns I
I took them home. Let them dry (picked up on a rainy day...I have no shame) .
Spray painted silver and...Tah Dah. I think they are gorgeous!

Tips for prepping natural materials:
1. Dry - Make sure they are dry before your use to prevent rotting.
2. Clean - If they are dirty, brush lightly with an old toothbrush.
3. Let them breathe - Don't seal in air tight bag...they may rot.
4. Reinforce - If they have a top on them like these lovely nuts, use hot glue to reinforce if they break off (and they do).
Will use as filler in my Pottery Barn knock-off of this - scheduled for Tuesday.
