we had a rainbow theme for one of our DDs birthdays. we had a rainbow layered cake and little cups of rainbow layered jellies. i think had cupcakes topped in different colours and arranged on the stand with little paper rainbow toppers that i made.

for the take home bags it was again paper rainbows that i made stuck onto paper bags with rainbow ribbons tying them up. inside were glitter glues etc.

for party prizes i went to smiggles and had as the Big Prizes those rainbow pencil cases as they had a 2 for 1 deal happening at the time. they were a HUGE hit for both the boys and girls.
