I have a notebook where I draw rug ideas, thoughts on color, possible dye formulas, and on and on. Do you have one? The key to making this book useful is to remember to flip through the pages on occasion. Doing this usually triggers more ideas, but more importantly, gets me to put some of these thoughts into action.
Lately, I've been fascinated with architectural details. I am particularly enamored of Matthew Rice's books on English architecture.
Keep in mind that the drawings below are very rough sketches, but I can see how they could be really fun to hook.
