For your shopping list, you will need:

1. decorators' tape,
   
2. sharpie pens (buy more than the team members),
   
3. multiple pads of small square post it notes (about 3" x 3"),
   
4. several sheets of small circular stickers in 5 or 6 different colours to enable voting,
   
5. little easy to remove tape to re-stick the post it notes that fall off the wall (sometimes they keep falling off depending on the surface you are using and temperature)
