I currently have them organized in drawers, as seen below. That calls for a lot of digging. They also get a little squished, and that does not do well over a long period of storing.
After watching some organization videos by Jennifer McGuire, and after adding pins after a Pinterest search, I decided that I definitely needed a sleeve or bag that made my stickers more uniform in size if I had any hopes of feeling "organized." This idea was very appealing:
I started searching for 6 x 12" ziploc bags, and what kept coming up was 6 x 12" page protectors.
"Hmmm," said I, "why not just go with what I know?"
It also helped that I had an Amazon gift card. So, for about $40 and free shipping, I will have 10 packs of these:
I was not feeling the plastic magazine holder vibe. Then I remembered I had two magazine baskets that I bought long ago. They are not the perfect width, so, I placed my stickers in sideways. I used what 6 x 12 page protectors I had to see how it would work. I think I will like it very much.
