Question
Can the table floral arrangements (for a wedding reception) be placed somewhere other than the center of the (round) tables in order to get around the problem of guests seeing over tall arrangements and/or one-sided arrangements?  Would this look okay or not so much?  Any suggestions greatly appreciated.

Answer
I don't think it will be a balanced look unless you
have candles or other items to place with the arrangements.
There are many ways to get by with guest seeing over the
flowers.  You can float flowers in a dish or make a
low centerpiece with ivy runners. If you are wanting
to make a taller piece, use a piece of curly willow or ting
so it doesn't block. A one sided won't do in a case like this.
Your going to have guest who see the back only. Good luck and if
I can help you let me know.
