We had a very small wedding (35 people) so there wasn't much for elaborate decorations. However, I was thrilled with how our centerpieces turned out.
I found the idea of using mini pumpkins somewhere online and loved the idea. I think the orange went well with our flower colours.
I also found a site that talked about kids activity books and I knew this was something I needed to do for our nieces, nephews, and my youngest sister.
They were each personalized and had various activities inside, including a mad libs, crossword, colouring pages, word search, and mazes. The kids really liked them and it's a great way to keep them entertained during all the "boring" parts of a wedding.
