CraftNerd there is no golden ring for organizing anything. The best advice I have ever seen about organizing anything is.......figure out how you use the things you want to organize and then organize them in a way that will be easy for you to find and use them......so for stamps for example how do you use them? Do you use them as sets, like to look at them as sets? Do you use stamps in categories, like hearts, stars, background stamps, flowers, etc.? Then organize them in whichever way you use them. Do you like to look through your stamps for inspiration? Then have them so you can flip through or look through them. Would you actually use a stamp inventory to find the stamp you want to use? If so it might be worth the time to make a master book of all your stamps. Put some thought into how you want to use or find your stamps and then try and find an organizing system that will work for you.
I have all my unmounted rubber stamps organized in plastic folder dealies that are made for scrapbooking supplies and they have held up really well. I have the cling stamps which are Tim Holtz, Dina Wakely, Dyan Reavely, and Paper Artsy in Avery Elle extra large plastic envelopes in plastic bins that I got at Ikea. I still have some in those albums that I have gotten at Hobby Lobby with coupons. So my stamps are organized in many different ways. I would think that if I did not have the folder thingies I would put my unmounted stamps in Avery Elle plastic envelopes by the same categories I have them in now and then into a bin like the other stamps. I would label the envelopes and then it would be easy to find the hearts, stars, Christmas, Etc stamps to look through. If I really wanted to get fancy (which I have done) I would stamp all the stamps on white paper and laminate it to go into the envelopes with the stamps in that envelope. It took a couple days and I have most of them done. I know that the Ranger cling stamps do not need to go into envelopes but some of the stupid stamps fall off the heavy plastic backing so I like to put them into envelopes so all the stamp sets are together and there isn't one in the bottom of the bin or one that falls out of the album when I am moving it. (Not admitting that I have had that happen and found it on the floor later) I did need to trim the hard plastic backing so the Tim Holtz, dylusions, and Paper Artsy fit into the extra large folders, but the dina wakely ones fit without trimming, does not make any sense.
I usually leave the stamp sets in the plastic they come in until it rips or breaks then put the backing paper and the stamps into an Avery Elle plastic envelope.
I am at work but will try to take some pictures of how my unmouted stamps are stored tonight and post them in case you want to explore the same sort of system.....LOL this turned out to be a book, didn't it?
