I'm so excited about rainbow themed party now and I haven't even Googled or been onto Pinterest! And I've just realised DS is 4 in less than two months....wonder if I can convince him to have a rainbow party theme...

Another idea for the party or take home party bags....Coloured curly straws, or, do what I always do and buy bendy straws then print out little pics, punch holes and attach (like bought ones but way cheaper and for any theme).
