Question
I am helping a friend with a wedding and she wants to use 24 inch tall vases.  She is on a budget, but she wants a floral arrangement on top.  Can you tell me what supplies I will need to make this happen for her?  I want to have them pinspotted with lavender lights...please help me!!

Answer
Dear Sheri,
The most straightforward way to get those arrangements with full flowers on the top of a tall vase is to tape a cube or globe of oasis floral foam to the top of the vase (sometimes it is easiest to get globes which will fit neatly onto the vase opening).  
Another way is to create a vase within a vase - find a shorter vase which will fit inside your tall vase.  Start to fill the tall vase with something small and decorative such as lavender, green lentils, or sand up to the level where you can put the short vase in, then carefully pour in more sand or whatever to fill in round the edges.  You end up with a tall vase with a short vase inside it but from the outside it looks like a tall vase. Then make a full handtied bouquet and put it into the short vase.
I think for the floral lights your friend may have seen FloraLytes - LED lights that run on watch batteries - I haven't seen these in lavender but try a google search as they may exist.
