Tips

  • Use a reference sheet for accurate details and building placement.
  • If you don’t have chalk pastels, brown paint can be used for shading and aging effects.
  • Always preheat your oven before baking the clay.

Common Mistakes to Avoid

1. Uneven Mortar Application

Reason: Inconsistent amounts of glue or other bonding agent between the miniature stones or bricks leads to an unstable and visually unappealing structure.
Solution: Use a small, controlled amount of adhesive and ensure even pressure when assembling the castle walls.

2. Ignoring Structural Integrity

Reason: Building upwards without proper base support or reinforcing inner structures can lead to collapse or warping of the miniature castle.
Solution: Construct a sturdy base and use internal supports (like small dowels or toothpicks) to reinforce taller sections.
