My cousin got married here in AZ, but her family and the groom's family were both from other states, so we threw together a quick, inexpensive luncheon for their wedding day. The centerpieces were yellow squares of material from Hobby Lobby (99cents), some petals, tissue paper flowers that were so easy to make, and a picture of the couple (frames were 3 for $2.50 at Target).
I made the cake and topped it with a yellow tissue paper flower.
For the sign in table, we borrowed a yellow bird cage for cards, and put a yellow candle by a framed picture of the bride and groom.
For very little money, and not much time to prepare, we pulled off a cute little reception for their big day!
