I'm having a post wedding party 2 wks after our wedding day(wedding is private, immediate family only, then off to honeymoon). It is in an enclosed park pavillion, catered, buffet style. Picnic tables will be have white linen table cloths. This is all DIY for decorations. I have 8" wide bubble vases, pink, white and green silk flowers and want to put lime slices in the vase, water and the flowers coming out of the top. Anyone try doing this? Any ideas on how to do it? I hear soaking limes in water makes them not float.
