This time, I used watercolour pencils rather than colour pencils. A much longer and tickier activity. First time ever. I have come to the conclusion postcards are too small for that type of colouring.
One great thing about coloring is the fact that it helps to fight against the dark winter days with their load of grey sky, pelting rain, drizzle and lack of light, without mentioning low temperatures. It might be better to use a drawing on a bigger piece of paper.
