Body | 1.5×2 inches | Primary color |
Arms | 0.5×1.5 inches | Match body |
Legs | 0.5×1.5 inches | Usually black/blue |
Advanced Decorating Techniques
After years of practice, here are my pro tips:

- Use firm fondant with tylose
- Create templates for consistent sizes
- Let pieces dry 24 hours before assembly
- Block Construction:
- Cut sharp edges using a ruler guide
- Paint details with edible metallic dust

Serving Suggestions
I always recommend these accompaniments:

A: Based on my experience, allow 6-8 hours spread over two days. Day one for baking and crumb coating, day two for decorating.
