My 3 aunts and my grandma hosted my shower. I got the aunts a big cancdle from Pier 1 ($8 each - Gma can't have candles in her assisted living place). I then got a 3 pack of small pic frames at Pier 1 and split it up ($10 I think). I got Gram a little photo album.
I always thought you gave a gift to someone who hosted your shower - relative or not...
