A wedding arch or chuppa can be a beautiful accent for any wedding, but they can cost a lot of money. HGTV's Sabrina Soto shows how to build one that won't break the bank. She starts with a pair of antique doors that she picked up at a reclaimed building materials store for less than $200. She decorates with inexpensive wildflowers and branches, which also hold up better than hydrangeas or peonies. For a freestanding chuppa, consider using straight tree branches attached with zip ties or screws and decorated with sheer fabric.
