I unmounted and organized all my stamps this past summer. It was a huge project and took me at least 6-7 weeks to get it done. I put all my stamps on acetate sheets, then store those in page protectors in binders. For myself, this is the easiest, most organized, and most cost effective way to have a system that works. I posted pictures of my system on my blog if you want to take a peek:
