Tie an autumn leaf (real or faux) with raffia around candles, place on a holder on seed corn (or popcorn kernels - or acorns) in tube glass or hurricane vases - arrange assorted sizes on a tray for a centerpiece
indoor living area with a chandalier, a cathedral ceiling and a beautiful opening to the outdoor area. ( I'd want this to be a "sun room" part of the house with window panels along the spaces in the cathedral ceiling).
Line: The book shelf in the room shows the use of line because the book shelf shelves are built against the wall forming a miniature tree. Our eyes are drawn to look at the book shelf tree from bottom to top and outward to the tree/bookshelf branches.
