At many weddings, the couple provides flip flops for guests who have come in uncomfortable shoes to wear while dancing. We refined that concept a bit. In addition to providing flip flops (purchased for $1 a pair from Michael's), we also provided cotton Mary Janes (originally intended as kung fu shoes). That way, the shoes could be worn with hose, and were less likely to fall off than flip flops were. We got some of them from the "Defected White Cotton Mary Janes" at China Direct Store and others from a classified ad by The People's Seller. The total cost was about $1.50 a pair, which made them comparable to flip flops in price.
We put all the shoes into two baskets, sorted by size. The signs on the baskets were made in exactly the same way as our "Closed" signs.
