Love this idea. Good for welcome drinks. Although... Our friends are... Rockstars. They may well crawl into the chapel :D Self-serve Mimosa Bar (or any cocktail drink works!) so your guests can add as much or as little as they want!
So many great things in this picture... fabric-wrapped boxes to serve as risers, a twist on the candlestick-cake plate with tin cake pans instead of a plate on top, candy bar and sweets table incorporated into one, nice use of metal loaf pans grouped together to display pops, clever mix of glass, metal, and fabric works really well.
Bridal Shower. This is a cute idea everyone at the bridal shower wears the colors of the wedding so if I did that everyone would wear white, ivory, mint, peach, coral, or really any shade of pink lol pastel blues and greens and any shade of gray.
