I'm going to be offline for a week so I thought I'd leave you with a challenge for anyone wanting to take part,
Look at the skies where you are and do a series of studies from life - different times of day, different weather. Really look at the colours. They don't have to be plein air - they could be simply out of the same window, looking at the changes.
Then leave links to your blog posts on skies in the comments section.
I hope some people feel like joining in :>) and look forward to seeing the results when I'm back online.
