Here is another colouring by numbers of medium level of difficulty.
There are eight colours in this picture.
Here are the instructions: you can see a number on each pencil. Choose the right pencil and colour the part of the picture with the same number.
There is not anything difficult here, is there? There is only one difficult thing. It can be a little bit hard to find all the pieces with the same number at once. So, you should look at the picture carefully. You shouldn’t miss any area in the picture, even the smallest one.
