1. Do you also save the zipped files?
Yes I do...mostly because I just never really get around to going back & deleting them
But they have definitely come in handy a time or two
2. Do you typically use each kit to make just one page, or multiple uses?
I don't have any "rules" about this... some kits I gravitate to more than others & use many, many times. Others, maybe once or twice.
3. Do you remove kits from your 'database' once they've been used as many times as preferred? Nope! (I did delete tons of "freebies" a long while back...but quality kits are keepers no matter what!
4. How do you handle kits that are retired/from retired designers?
My kits are in folders by designer. I put a 0 in front of all of the non-retired designers so their stuff stays on top. I also do the same thing in my kit previews folders (I copy the previews & put them in folders like "everyday", "winter", "travel" etc.) Then when I am scrolling through, if I'm doing something that I want to count for a Passport stamp, etc. I stop scrolling when I hit the previews that don't have a 0 in front of them. When a designer retires, I just delete the 0 from the file name.
