Do you have a collection of dried leaves, a drawer full of toe nails or bag of random pebbles you've been hoarding for years with no real purpose in mind? Well, your moment has arrived. The Wellcome Collection are looking for Londoners to present objects, ideas and stories for this weekend festival of collecting.
The most interesting items will be selected to go on display at the new exhibition 'A museum of modern nature', opening 22 June 2017.
