Why 2 lists? I use the numerical order list to mark my catalog. It makes it very easy because the stamp sets are listed by page number. I use the alphabetical list to check my shelves for retired sets. This works well if you store your sets in alphabetical order.
This year, I'm sad to see Wild Rose retire. I made Isabella a name frame with this set before she was born and it still hangs in her room. It's such a beautiful set!
