I dug around in my computer looking for good examples. For some reason I expected to have more pictures, oh well, but here are some:
I love votives! There's never too many. You can line a window still...
Candles around the centerpiece or part of the centerpiece
Square votives with square centerpiece
Square vases with floating candles surrounding the cake ~ notice the different heights
Square centerpiece with circular votives ~ it works
Bridesmaid bouquets in vases ~ use as head table decorations
Votives adding light to the guest book table (from knottie ccla)
