There are tons of other neat objects available that you can use in a Rustic or Retro themed wedding.
How about vintage drawers to hold your escort cards? A-H in the top one and I-Z in the bottom. Or get all four and split across four drawers.
Strawberry baskets for your centerpieces?
Or a pet carrier to hold programs or cards?
What about an ammo crate to hold umbrellas for an outdoor summer wedding?
Best thing about repurposing objects? You're making green[er] choices. You can have unique decor at reasonable prices. And if the objects you choose match your own design aesthetic for your home, you can reuse the objects for storage.
