I got the loveliest email from Jo and her class about their own adventures in chalking, and she was kind enough to give me permission to share the story here. (Hi class! You guys are fantastic chalkers!) It put a huge grin on my face; I hope it does the same for you.

[Jo says.... ] I asked them what they would write if they were allowed to. Some just wanted to see their name, others wanted instructions (danger road!) but most of the girls wanted to make people smile with cool pictures and nice words.

We had a good chat about graffiti and how this version was not permanent and all the better for that.

Then they got into groups of two or three, chose a word or a phrase and set to. We decided to have a go in our 'secret garden' so that it wasn't so public as it was our first try.

The results are amazing. Some of the children started small and then discovered they had no limitations; it wasn't like using a piece of paper. we were out for a hour and everyone concentrated for the whole time...not bad for a group of seven and eight year olds.

They were so delighted with what they had done, they wanted to show everyone. The best view was from an upstairs form room but you had to get close to appreciate the detail and the joy in every inch.

Sadly the rain came a few hours later, but not before we had recorded our 'adventures in chalking'

Hope you like the results ... We are now plotting more 'Phantom chalking'
