How do you organize your stamp sets?

I organize by brand and then theme within the brand. I do have all my cover plate dies together. But I separate by brand in there. I use the stamp market organization system and fridge bins. So I can easily see my brands and sub categories.

For shaped dies like circles, rectangles, etc. I have large magnetic sheets I got from stamp n storage. I put those on open frames. I store all my rectangle dies on one, circles another, etc. if items have stand, dies, stencils, I keep them all together in the same storage pocket. If I have several items of one collection I have it by brand with a divided tab with the name of that collection so I remember all those items go together.

I’ve been collecting stamps longer than some here. I started stamping when I was a young mom, and I was a stamper before I was a scrapbooker. I have often incorporated stamps into my layouts. Because I have been collecting for decades, I have a huge collection. Before we moved halfway across the country 8 years ago, I knew the weight of all of my wood mounted stamps would be an issue. I unmounted and converted them to peel & stick stamps and organized them mostly in the now discontinued PSB zipped binders. Sadly, PSB binders are no longer available, so I’ve had to put some in zipped school binders, which I don’t like as well. They don’t hold as many stamps, and they have extra bulk with pockets. I rarely feel a need to buy stamps anymore.

For each binder, I stamped images on a sheet of card stock, put it in a plastic page protector, then stuck those stamps on the back side of a plastic sheet, which I slipped inside the page protector pocket behind the stamped sheet.

I have mostly sorted my stamps by theme, although MFT and G45 have their own (school) binders.

When Close to My Heart changed their stamps from wood mounted to the peel & stick stamps that were in plastic envelopes, I started buying them and their containers, which I loved. Again, I sorted by theme, and labeled the containers. I keep them separate.

Despite my huge collection, I can find what I want for any project very fast. Even if there were no more scrapbook stores or craft stores, I could keep scrapbooking forever. I would simply stamp my backgrounds, as well as my embellishments. I sometimes do that, anyway, when I can’t find the right paper in my stash. It’s not as fast as using store bought papers and embellishments, but some of my favorite layouts are those where I stamped my background paper and/or embellishments.

I organize by theme. I would never remember everything I have just by brand name. And some brands I have very few, so that would be silly.

ETA: My theme are a little more specific than yours:

Example:
Holiday / Seasons
Floral / Foliage
Alphas / Numbers
City / State  - for Kerri Bradford/Studio Calico type stamps
Sentiments

I have more that I don't remember right now. But in the end I guess it would depend on what type of stamps each has. 

You’ve probably heard it before but it helps to think about how your brain would describe the stamp - does brand come first when you visualize what you’re looking for or do you go looking for a birthday stamp and then narrow down to brand? And do you like the serendipity of browsing or do you like to find the exact stamp you have in mind asap?

My experience isn’t much help because I don’t have a big stash and mine are sorted into bigger stamps at the back, smaller sets at the front, and sentiment, background, and Xmas stored in their own little sections next to that. When I forget that I reclassified my fall leaf set as a background I only waste about a minute leafing through all of my image stamps twice before I remember.

I had mine loosely arranged by brand within the sizes but I’m absolutely terrible at putting stamps back in the same spot (I often leave the one I just used at the front so I will remember what I wanted to do with it next) so that’s also a consideration.

Mine are currently sorted by size, and that works okay for now, but I don't think this is the final iteration of organizing for me. I think I would prefer by theme and will head that way eventually.

I organize by brand.  I also formerly used Evernote and now use Bear App to catalog my stamps with a full image of the stamp set and coordinating dies.  I also catalog my stand alone dies, stencils and embossing folders.  Using tags to search for something is AMAZING!.

Theme, labeled in clear bins and envelopes. There are bins for just stamps then bins for stamp and die sets, organized by theme in clear envelops with magnetic sheets, stamps in the front of envelope, dies on the backside of the envelope.

Solo dies are the same but with the magnetic sheets in the envelopes.

Now stencils and embossing folders, each have their own bins but no organization.

I too am a clear envelope in a clear bin girl.

I organize free standing dies separately from stamp and die sets. Foil and press plates (I don't have many of them) have a small shared bin.

Then within those I organize by category.

Right now I do have two lines separated in their own bins because I have quite a bit of them from events. They are PinkFresh and Concord and 9th. One day I may incorporated them it with the rest of the stamps and dies, but for now it works for me.

Mine are organized by brand. 

For those that organize by theme, what do you do when there are sentiments and florals or other images besides sentiments? That's what gets me.

The mentions of Bear & Evernote reminded me to mention that putting all of my craft items (not just stamps and dies) into the Color My Life app was an absolute game-changer. Love that there’s a spot for you to enter the item’s location and you can be as specific or broad as you like, and there’s a note feature that I use often, especially for things like “has a matching die set” or “in same pocket with Such-and-Such stamp set from same company”.

Keyword searching is how I start out if I know I want to create a certain theme of card or layout but want to quickly glance through what I have that matches that theme or has a specific sentiment like “Thinking of You”, which is in a zillion sets, but I might gravitate toward one style or font over all the others.

It’s a bit of work to get everything entered into the app from the beginning, but super easy to add a few items here or there as they come in, and my goodness, it’s so worth it to me to be able to optimize searching without digging, and knowing immediately what all of my options are.
