Refrigerate the ham, cheese cubes, and tomatoes for at least 30 minutes before assembling to keep them firm and prevent the cheese from sweating or sliding off the skewers.

Roll or fold each ham slice into quarters before threading onto skewers rather than using flat pieces, which creates better stability and a more elegant presentation.

Pierce tomatoes through the stem end rather than the side to prevent them from cracking or sliding during assembly and serving.

Alternate components in a consistent pattern (ham-cheese-tomato-ham) to create professional-looking skewers that are visually balanced and easier to eat.

Soak wooden skewers in water for 20 minutes, then lightly toast them over a flame for 10 seconds to seal the wood and prevent splinters while adding subtle flavor.
