Organizing ephemera? What is your system?

If I have the collection, or part of it, I like to keep the ephemera with that collection. But, I'm finding that storing them together isn't really working for me either. So, I'm not sure what my solution will be.
Misc. ephemera I throw in a 13x13 storage tote. When I am looking for some additional pieces to add to a page or a card, I grab my ephemera tote. Along with that, I also have a tote for enamel dots, one for wood pieces, one for tags, one for journal spots, one for doilies, one for word phrases/stickers, etc.

Mostly, mine are by theme. I have some theme boxes (Christmas, Boy, Girl, Summer/Outdoor, etc...) and they go in those. If they are generic, I have some generic areas too. I try to put stickers, papers, embellishments, etc in those boxes.

I have to quickly see my diecut options to use them. I’m not motivated to open the pack , spread them around, flip them right side up, rotate, just see if there’s a few that’ll “work”. Then gather them all back up to put back in the package. Such a hassle.
I’ve been getting white card stock and sticking the diecuts with a smudge of dot roller adhesive. Then slide that into a pp. I can see them all at a glance. My hand can fit inside to unstick the one I want w/o pulling the whole sheet out.

for bulkier items, i have a 60-drawer card catalog.  for die cuts and small pieces of paper. i have them separated into baggies and stored in a box i can taken on or off my desk. i have a couple of specific boxes for christmas, halloween and travel.

I almost always scrapbook by product line. So I store my embellishments in Iris cases by manufacturer. Often I will twist tie together packs from the same line so I can just grab it when working with the coordinating papers.

I separate all the ephemera packs right after I get them.
I have separate pockets for flowers, leaves, big titles, fruits, animals, butterflies, tabs, tags, labels, leaves, arrows, small words, hearts, stars, tickets, speech bubbles, birds, etc. I also have a box for random pieces that do not belong anywhere like a random rainbow or a kite. If i have a lot of one kind like flowers or hearts, i will have some subpockets. I also keep some ephemera packs together if they are very themy like birthday packs. My Christmas ephemera pieces are separated similarly but are not stored together with the rest,
except general labels.
This storage system worked well for me and i usually take away any pieces i know i will never use. I collect them and sell them and they have been selling well for people who have young kids scrapping who do not care so much about the actual images so random cactus wearing sunglasses or a merkitty is ok.

I use two different organizers for ephemera.

The first is a Die, Stamp & Supply Organizer by Totally Tiffany. I keep 12x12, 6x12 and smaller sized sticker/chipboard/ephemera packs that I haven't used enough to be broken apart yet. They are sorted only by size. I know what I have and what area it's stored in so it doesn't take long to find what I'm looking for. In the front row two sections hold project life/journaling cards. I've almost used up enough that I can combine them into one section, and then gain a section for more die cuts!

The second I use are clear cosmetic/jewelry cases from Amazon. I have three that live on my desk just beyond a 17" x 23" cutting mat. The large drawers are sorted by color. Only purple is in a small drawer. The other small drawers hold numbers, wood, and multi-color.

New die cuts/ephemera packs start in the Totally Tiffany organizer and once I've used 50% or more, I break the package up into the rainbow drawers (and toss or pass along anything I won't use). I'm not typically a themed/collection scrapbooker, so this system works well for me.

The only things that don't go into this system are Christmas and Halloween - they each have their own system.

I have clear 8 x 14.5 x 2 containers. I also have them 12 inches wide. I keep several sets of ephemera in each container. So Outdoors might have 6-8 sets in one container. I also have 12 x 12 envelopes that have ephemera on them that I can pull out.

I keep all embellishments together by theme.

My themes are each stored in a gallon sized (or two gallon sized, if it includes 12x12 paper, like "zoo" or "graduation" themes do) .

I buy stash with themes in mind, and anything that is just shapes would go in random.

Having one bag per theme is an easy way for me to limit my stash size too.

I store mine in the small Avery Elle pockets. I used to use the 5x7 photo containers, but it got too bulky for me, so the pockets are a nice compromise. I'm pretty picky about ephemera: when I get a new package, I immediately go through and remove the random stuff I know I won't use. I mainly store mine in these overall categories:

Sentiments
Shapes
Collections
Holidays

Within in each category, I have separate pockets (e.g., for sentiments: birthday, compliments, hi, etc). For some collections that I really love, I will keep the whole pack together, especially if it's something that is so specific to that collection, in regards to either theme or style.

Disclaimer: I'm a cardmaker (former PLer), so my needs are different from a scrapbooker, but I thought I'd still share.

Plus I really like seeing the kids old drawings when I'm flipping through them!
