Spacers will help you roll out the paste evenly.

You can use: 
  • Lollipop sticks (1.5 mm)
  • Candy floss sticks (4 mm)
  • Toffee apple sticks (5 mm)

When use spacers?
  • If the edge is going to be exposed.
  • If you want all parts to have the same thickness.
  • If you want a certain part to be level.
