Some additional hints about that method – we use 16 lb paper, which is much thinner than regular copy paper, and we find that it adheres really well while still being reversible. Also, we print a lot of our labels sequentially, and sometimes need to assign hundreds of numbers for our archaeological collections. We can do this in a matter of seconds in Excel, which has a function that will autofill numbers in ascending or descending order. I know it sounds cumbersome to some, but the time and eye strain that it takes to cut them out really isn’t much more than it takes to write a legible accession number on a small object with a steady hand. Good luck!
