Keep the meats surrounded by cheese, nuts and maybe olives. Don't have the meat touching veggies or fruit. 2. Do not use anything that turns brown. For example, apples and pears aren't the best choices for fruit. 3. In Summer, it is great to use fresh berries, but they tend to let fruit juices out. Put them in a bowl on the board, so it doesn't compromise foods around them. 4. If you are running out of room, put the crackers or pretzels in a bowl on the side instead of on the actual board. 5. Serve toothpicks or small forks and knives on the side to avoid people touching everything.
