Creative Haven Beautiful Trees Coloring Book

This is a new way of colouring I hadn't seen - black background with the items made up of very small blank lines and squiggles. I have no idea if there's a name for this style and it works well for trees. Once you choose your colours you can mainly get on with it, but some object boundaries can be hard to define. However they deceptively take up a lot of gel ink if you use this. I haven't tried pencil yet as I prefer the intense colour and smoothness of gel pen for fiddly colouring, mostly glitter. The silver birches will be pencil because of the need for white on the bark. There's a tiny name label on the bottom left, beside the perforation. Although the introduction mentioned name plates, it took a while to spot them. They are a big help.
