I found it actually more important to make a spreadsheet of all the dies, with their measurements and die number, with description so that you will be able to know, at a glance, whether you have the proper dies to make a project.
I found this invaluable when looking at a pattern that calls for specific size dies.
Then store them numerically in order, if possible.
I am actually thinking of making another spreadsheet for all my quilting books. So many times, I see a photo or quilt made from a pattern in a book, and think, "I have that book". But do I, really? It would be so helpful to have that information on my laptop in a spreadsheet....
