These would make great décor or accent pieces at your wedding reception. Get some frames from a yard sale or a thrift store and paint them to match or compliment your wedding colors. You could put flowers in them hang crystals from the inside or even use tulle with lights. After the wedding repaint them to use them in your house or keep them the colors of the wedding as a reminder of the day.
I had the honor of working with Sarah and Shaun on their wedding that took place on July 21st. They are a great couple that had to put of the wedding for a while because their youngest daughter was diagnosed with cancer. They had a beautiful outdoor wedding at their home in Freedom, with the ceremony by the pond and the reception in a tent.
She had blue and pink for her colors and used a few fancy linens to add that special touch. Butterflies were also part of the theme and she had some centerpieces with floating butterfly candles alternating with blue and pink sand centerpieces.
