How to make cork wedding table numbers

I designed these on the computer as I did with all the other stationary projects.  I then had the local print/copy center print them on the same creamy shimmery paper that I used for all my stationary.  I then mounted them onto a dark brown paper cut about 1/4" larger to create a border.  I carefully cut the corks to hold the card.  Once placing the card into the corks, I quickly realized it wasn't stable enough.  I then added a 3rd cork to stabalize the stand by glueing it with a low-temp glue gun.
