I said once in a chat that I would post pics of this. This is what we did with our wine corks one year.....
Dave just drilled a hole in each one for me. Then I used heavy floral wire and beads. I bought garland already made and took it apart. It really wasn't that expensive and the garland has held up REALLY well.
We save wine corks during the year and I try to label them with a permenant marker as to what we were doing while drinking the wine . Like :Wrapping presents Dec.18, 2006 or New Years with Jamie 2006. It's nice to see the garland on the tree and have the memories come back.
