BINGO.
I found some pretty cool online tutorials, but I thought I'd share my own below.
Wine Cork Place Card Holders
1. Buy 100 bottles of wine (remember, you'll need one bottle per guest!)
2. Open and drink 100 bottles of wine. Save the corks if you're not too drunk to remember this step. Keep drinking until you have enough corks!
3. Take 4 weeks to sober up, and/or be released from the hospital.
Or you can...
1. Go on EBay and purchase a bulk bag of 100 corks for $10.00.
I wouldn't recommend the first set of instructions unless you want to spend a lot of money or become a raging alcoholic.
Now, take your corks one at a time, and set them up in a vice-grip if you have one. It is much easier than trying to hold all the corks while trying to cut them. Cut off the bottom 1/3 of the cork and discard. Run a piece of medium grit sand paper over the cut surface. Finally, make a slit in the top of the cork deep enough for you to insert your place card.
VOILA! YUR DUN. And all for $10! With that extra $90, you can go buy many cases of vino from Total Wine!
