This giant flower installation has been made out of painted egg cartons and lots of string. (around 2000 of them!) The first stage of the installation is to buy lots of egg trays. Any wholesale place has them available fairly cheap. Each cup needs to be carefully cut out - this is a little tricky as the cardboard is tough to cut through. Then the cups need to be painted and the final stage is to string them together by pushing a pencil hole through each egg cup. Tie a small piece of wool inside the cup to stop them sliding to the bottom. You need to purchase a lot of green gardening yarn to hang them floor to ceiling. To hang each string, I used wire baking trays.
