With the holidays just around the corner, I'm dying to start decorating for Christmas. (I have a no decorating till Dec. 1st policy, I mean, lets enjoy Thanksgiving first!) But I can always craft to get started on Christmas. I found the Styrofoam tree form at my local Dollar Tree. The ribbon and flat pins are from Wal-mart and white pins are from Hobby Lobby.
Cut the ribbon into 2 inch strips. Mark off every 1/2 inch around the foam to ensure a uniform look. Layer the ribbon on top to cover. Fold ribbon in half, pin in place. I did burn the edges of the first layer to keep it from fraying. Then using my marks as a guide, I pinned ribbon in a straight line to make each layer. I used flat pins so you wouldn't see them. I used 2 rolls of ribbon, about 250 pins and it took about 2 hours since I was just making it up as I went. (I spent a lot of time burning the edges of the ribbon that I didn't need to do.)
I put mine flat on the shelf, but I as soon as my decorations come out, I'll probably put in on a candle stick or something. Let me know if you make on too, I want to see what you've done.
