I have a household notebook that I've used on and off, but my binder and dividers aren't stamped. Not yet, anyways... I just hadn't thought of it yet. ;)
My section dividers are made from scrapbook paper, though-- 8x11.5" size in clear page protectors, with stick-on tabs used to label the edges. The cover is a store-bought blue with a pink breast cancer ribbon and pink stripes.
Mine is set up Flylady's way (
www.flylady.net) with some of my own forms also in it.
