Here is some inspiration for a Rainbow Party. You could also incorporate a lot of these ideas into a St. Patrick’s Day celebration.
Cupcakes; Rainbow Jello Snacks; Small rainbow cake; Rainbow fruit spread; Rainbow pasta activity; Long Rainbow cake; Rainbow straws; Circle Decorations; Rainbow Soda Station; Rainbow of flowers

Thanks for the pasta shoutout! It was such a fun party.
