Use what you have on hand; think rustic large cutting board, large flat surface platter, or even a plate charger.
Begin at the edges of your base and place a rosemary branch at the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock.
Begin by threading salami onto bamboo skewers along with cherry tomatoes and some harder cheeses like parmesan.
Just like you did with placing a rosemary branch at the 12, 3, 6, and 9, so too place a single skewer at the 1:30, 4:30, 7:30, and the 10:30.
Once the skewers have all been placed, go back in and fill in the gaps and empty spaces with grapes, nuts, chunks of cheese, halved fresh figs, pieces of chocolate or cookies or petit fours.
