Start with large board, using one with edges is easiest. Place the bowls for the dips on first and the Brie cheese or other cheese you're using.
Add the largest items like the watermelon and pineapple slices. Spreading out to more than one spot on the board if possible.
Next, add the medium size items like the crackers, bread, small cheese cubes, and sliced salami. Add in other medium items like vegetables and other fruits.
Fill holes with smallest items like grape tomatoes, blueberries, blackberries, cheese straws and chocolates. Cover and store or serve immediately.
Notes
Prep/chop/slice everything ahead of time. This makes for very quick & easy assembling.
Make sure your board is big enough to hold everything! One with a lip or rim is best.
I like to start with bowls and then fill in around them. I've tried it the other way and trust me, it makes a mess.
Fill in gaps on your board with more fruit and nuts. Or some lettuce leaves for some extra color.
Get a little of everything (sweet, spicy, salty, savory, crunchy). Keep your people coming back for more!
Don't forget toddler snacks like Cherrios or Goldfish crackers.
