We are putting together rectangular tables to make long rows. I think the tables are 10 feet if that matters, but we will be putting 2 or 3 together per row. How far apart should the centerpieces go on long tables? If I figure 2 per table, That's 4 feet apart. Is that too much? Or do 3 at 3 feet apart? Naturally less is better for my budget. And what do you put between centerpieces like that?
