I found a post @ http://www.thesweetestoccasion.com/2011/01/wedding-brunch-ideas/ for having a brunch. How cute are these pancakes! I also love the idea of a pancake station, with various toppings.
This second idea of a bisuit bar that I found @ http://ellybevents.com/blog/tag/inspiration-station/ looks so good! I also really like the vintage decor and fresh flowers.
When I found this last post @ http://www.jepromets.com/2011/05/brunchinspired/ I just loved everything about it! I really like the fresh flowers, big and little chalkboard. The way the food is laid out is great as well.
Combining vintage, rustic and pretty colors for the decor is the way I would go with this. I think the idea of brunch for a bridal shower would be a great way to relax and have fun for the bride and her guests.
