My little washing-up helper

To make the box pretty and to be able to hang it, I glued a (nylon) cord around the upper edge which I then connected to the lower edge.
 
In order to attach the cord to the back of your box, form a small loop (stick it with a piece of adhesive and you get a loop).
 
You can glue the decorative hook to the wall tile of the kitchen using double-sided tape and hang your box by the loop.
 
In your little box, you can easily store your brush or sponge for the dishes, the excess water will flow into your little can and so your sink will stay clean.
 
Then nothing is easier than to pour out the accumulated water, rinse the little can and that's it, Agnes is ready to start the next load of washing up.
