Wine Stamped Invitation 

You'll need
4x6 sized invitations
4x6 sized envelopes
computer + printer
1 wine glass
1 ramekin (large enough for your glass bottom to fit in)
a splash of cabernet or merlot (a wine with enough pigent to make a 'stain')

What you'll do:
Step 1: Print out your invitation information on the computer. Be sure to align the information all to one side.
Step 2: Pour a small spash of wine in the bottom of a ramekin.
Step 3: Dip the bottom of the glass in the ramekin. Be sure to coat the entire rim of the base and let any excess drip off.
Step 4: "Stamp" the bottom of the wine glass on the invitation. Stamp as many rings as you like - just be sure to re-dip the glass between stamping, shaking off excess.
