I am a nester, and I love to arrange and rearrange. As a kid I never liked to do puzzles. I still don't like to do puzzles. I have never liked that with jigsaw puzzles, there is only one way to put them together. While it is certainly satisfying to find two matching pieces and assemble them, I have always hated the rigidity of it all. It's the same reason I don't like sewing clothing. It's just too systematic for me.
But arranging visual elements in a composition or an apartment? That I could do all day. While I think that there are wrong answers (mauve drapes), I do think there are endless possibilities.
