Can I mix different icon styles in one deck?

No. This is the #1 sign of an amateur presentation.

  • The Mistake: Using a thick black outline icon on Slide 1, a colorful 3D icon on Slide 2, and a flat gray icon on Slide 3.
  • The Fix: Pick one style (e.g., “Thin Line Style” or “Flat Filled Style”) and stick to it from the cover slide to the “Thank You” slide.
