Working with a basic Attic Windows background and photos and sketches of modern and historical Mexican pottery, I used a big sheet of graph paper to plan my shelf of pots.  I realized that it was looking like a tic-tac-toe board: pot, pot, pot.  I decided that adding a rosebud in a vase in one space and a pot with hanging ivy that would drape through several shelves would soften the look.  The next step would be to fussy cut the pottery fabric and chose colors for the shelves.
