Jan, I also really like your backgrounds! I think there is a range of looks there, but they are all nice. At this point, I really don't think there is an absolute correct way either and why not use many different materials!?
If were talking about it, I am not married to the idea that there is going to be an absolute correct way to do Bokeh. I think there area variety of ways I have seen it used in photos, and why not have a bit of a variety of looks for papercrafting too?
Thanks for participating and I am really enjoying the great dialogue!
