We were married last June and I am finally ready to part with my boxes of centerpieces taking up the basement! :-)
We went with a rustic type centerpiece (not sure how to add a pic on here, or if I even can) but I have:
2 different sizes of cut aspen logs: (like 6 inches tall and about 2 inches tall). They have twine wrapped around them (easy enough to take off). A box of floating candles, large vine balls and a lot of small vine balls. We had enough for 12 tables. I think we have some votive candles as well and some tall cylinder vases and fake fern leaves.
Sorry for the description (it looked a lot better than it sounds from this!), but PM me and I can get a picture of what they look like to you! And, they don't necessarily have to go together, pick and choose what you might want! :-)
