You bring up a great point about the hangtags!! What I do, since I need to keep track of what I spend for ebay profit analysis, is I take the price tag off the bag, and I thread the hangtag chain through a little hole I make the price tag, and write the name and style/creed#'s on the back of the tag so I can always rematch them up later and fill in my record books, etc. I stick all those hangtag in their own recycled baby wipes box which has that handy little opening in top for popping in tags... and I keep it in my laundry room where I do most of my rehab work. Any old box, shoe box, etc. would work. IF the bag doesn't have a tag attached, I just keep scrap paper handy and quickly fill out my own bag/style information on it and attach it to the hang tag for later match up.
Hoooolleeee cow...You are one organized woman!
I wish I were that organized.
