I´ve seen a lot of paintings lately where the painter has used several canvases to make out the whole picture. Yoy can then put it up on the wall, hanging them up with a narrow intervals between them.
I gave it a go yesterday, painting what i would like to be a tropical beach along a distant coast.I´m especially happy with the Island in front, and not so pleased with the rock formations on the right side. It looks a little cartoonish. But all in all i think it´s ok.
