Just a quick one today as it's my birthday. I got out some of these little bubbles yesterday at the teaparty, but they were originally made for our wedding tables. Each person had one and the ribbon tied around them matched our invitations and other wedding stationary.
The bubble pots came from a website and were incredibly cheap (£4.99 for 50 or 100, I think) but they provided some nice entertainment between courses. You could adapt the ribbons to match whatever colour scheme you want too!
