I kept the decorations simple, but these Pom Pom's are super cute and very easy to make. I found the instructions at Martha Stewart's website
The Birthday banner was also very simple and even comes with a printable template. I printed the letters out onto coloured card stock and weaved them through some ribbon.
I bought some purple flowers and out a cute cupcake ribbon on the vase, and used my fancy 3 leveled tray for the sandwiches that we served for lunch, along with(not in picture) some fancy white tea cups and saucers that were lent to use by some great friends.
