These stones are an alternative to paper place cards, escort cards, and table numbers. Awesome idea as they double as wedding favors! Affordable too. :o)
Also once you are on Etsy...there are so many ideas...just click on the weddings tab.
Congrats on your big day!
You should start with getting ideas if you have a theme. I save lots of money from the place I had my reception, they already had lots of things that I could use for my tables. I gave away bamboo in a small glass, I made these all myself. My reception place provided a mirror base, candle holders (I brought the tea lights for them), some colored rocks/glass, & sea shells that I brought in bulk. You will see that you really don't need too much as a centerpiece. It all depends on how it's put together. It never hurts to ask the reception place you are using if you can use anything they already have. Hope this helps.
as far as favors go, I made a candy buffet so people could make their own favor with the color cordinated candies. i also made my own centerpieces.
