What you will need:
1. A circle die cut or punch
2. Colorful paper- metallic and a sparkly
3. A sewing machine and thread
The how to:
Step 1. Cut out a bunch of different colors of paper with the hole punch
Step 2. Organize them by color in the order for the garland.
Step 3. Line backsides of circles together to make it go faster.
Step 4. Sew them together.
I think a Christmas tree full of these would be so effective, mental note for Christmas 2012.
