I've just discovered a fab new brand of crayons by Bambino. When I'm creating colouring sheets I always love trying out new art materials I can use in photos and workshops. I've pretty much avoided crayons, particularly wax as I dislike the texture and mess, then I spied these new clay formula crayons and I just had to try them. I've used them to colour in an Afternoon Tea themed colouring sheet I designed last year.
