I used Caran D'ache watercolour crayons and acrylic paints.
I just wanted to say thank you for all the lovely comments about my son. He has spoken to his year head and has to fill in a form from student services and then the year head will deal with it. Hopefully it will get sorted, if it doesn't I will go to the school. I want to give him the chance to sort it out himself before I step in!
