Please link you post to mine in time.
Submission period is between the 29th of June and the 7th of July .
(11:59 pm CET)

I would like to ask you all if you have any ideas for topics for the following months. I am sure that each and every one of us has this one (or more) topic she wants to see transfered into a picture by us all. It would be great if you would leave me a comment and tell me your favorite topic so that I can include them in our Photochallenge!
