I keep a record of my larger quilts and wall hangings that I make. I also put them in the clear sleeves in a 3 ring binder. I also have 3 ring binders for pics of all my projects (it's a bit behind at the moment) and of my WIPs.
I also have a journal started of my 'history' of quilting. Since I'm fairly new it's a short history. But someday my grandchildren will be able to read about me and my quilting.
no1jan - you are way tooo organized. I never thought of a spreadsheet for my fabrics and magazines and books. Good idea thought. I have photos of all my fabrics that I take with me when I go shopping for more.
