I think one of the real addictive issues about these cards is the making of new friends (on the net), and one (whhooo!) becomes used to mail from these new friends landing on the doormat as the postman passes. It is the swapping of the cards which is the truly addictive part - not the making of them.
Having decided this, I feel much better about the addiction than I did. After all there is nothing wrong with making friends. And the swapping of the physical cards is far more interesting than simply swapping blog posts on the web. (Please do not feel offended by this remark, as no offense is intended).
Of course my theory falls down, when I remember that I started this addiction by painting and selling ACEO's on ebay, but was this simply to make money - if so then it is not a well founded premise as anyone selling these on ebay will testify. But I did get sort-of tired of painting them and very readily turned to collage and swapping.
Here is my latest batch:- the first is another waterfall card - a simple almost monchrome card pandering to the ladies who love cats. This is called, "Feline"
