What you'll need:
- Cardboard; you can get this from cereal boxes, or buy card stock at an art store.
- Blue painters tape; you can use regular masking tape, but I find it may take away paint from models.
- X-acto knife and scissor
- Pencil or pen
- Steel ruler
- Cutting surface
Copy your design onto the cardboard. Blacken in any areas you want to keep or cut out. Just remember to be consistent.
Use your X-acto knife and steel ruler to cut out the designated areas.
Place some blue painters tape down on your cutting surface. You can overlap tape incase your template is large and you need more room.
Place your stencil template over the blue painter tape, and use your pencil or pen to mark the areas that you will be cutting out on the blue painters tape.
Using your X-acto knife and steel ruler cut out the shapes on the blue painters tape.
Your blue painters tape is now ready to place over your models or terrain.
You can keep reusing the cardboard stencil template as many time as you need to repeat your design over blue painters tape, cardboard or polystyrene sheets.
Note: The blue painters tape will begin to lift up if you leave your template on a model or terrain piece for a long time. Run your fingers over the blue painters tape before beginning to paint if you left it sitting around for a while.
