The Tuesday Inspiration” began in 2009 when two PB members - Helen and Stefan - started setting each other a challenge on a… Tuesday. Very soon afterwards, it was decided to open this up to other PB members, followed by the idea that we should not reveal what the subject is, so that other members could compare how different members view a single theme. The Tuesday Inspiration is not a contest or a challenge, but a group of people all agreeing to post their interpretation of a single theme on Tuesdays. Each week, one of the contributors sets the theme. There are now over 40 members contributing to the TI. We have only two “rules”: don’t include the subject in the TI title or tags and please comply with standard PB guidelines on courtesy, etc. If you would like to take part, please contact Helen (Girafferacing).
