Sometimes I'm getting crazy when I see how many duplicate of the same object we accumulate. In our home (with kids) we have at least:

20 pairs of scissors

30 kitchen knifes (table knifes not incl.)

8 Swiss army knifes

20 drink bottles

Hundreds of pencils and markers

7 matress (normal ones) + 4 inflatables ones

20 bed sheets

10 polar blankets (in an overheated modern appartment)

20-30 kitchen towels

25 pool and shower towels

15 backpacks

12 balles (toy of the kids)

8 bicycles

7 skate scooters

...

I could continue like this for hours.

For some times I have been thinking about making a little art project and gather one kind of a given object with a single utility and photograph them on a table or on the floor. It will end up with a photo series to show the ovet consumption in our modern society.
