changing -little- things

My desk is full of notebooks: sketches, lists, office stuff... whatever it is, I have a notebook for it. When I buy them I look for the black ones but sometimes I urgently need new notebooks and no black ones are to be found. Then I buy what is available and redesign the cover, as I showed here once. For the last ones I used masking tape and I really love the result, especially this black-silver-green one. There are few blank sheets left, so I'd rather be thinking about new designs.
