I found the lines for this dragonfly on an internet website with free colouring pages. This time I inserted a sheet of drawing cardboard into my printer, being a bit anxious because I was not sure whether it would take it or not. It did! It is not a super heavy drawing cardboard but it was strong enough not to buckle during the process of activitating the watercolour pencils.
I am quite satisfied with the result, but there's one thing I find disturbing: the patch of dark blue on the back of the dragonfly. I think it is too much of a contrast.
