Get rid of all the things you don't need/wear anymore and organize a flee market: the income will be donated to a non profit organisation An idea from Elena Morena

This should be the idea for april next year! In the Netherlands every year at April 30th a big fleamarket is being held allover the country (because of the Queen's birthday, or actually her mother, well long story). And then ask friends and neighbours to give stuff for the flee market. Selling on a flee market is actually a fun thing to do.

I've heard about Queen's Birthday ;) I will repost the idea!
