I don't know about other countries, but here in the United States, there are lots of reasons why people might own collectible cards, from sports, to games like Pathfinder, Magic: The Gathering, and Pokemon. And of course, if you have a lot of cards, you need a place to store them. When my last attempt at clothes organization didn't work out (three ring binders,) I decided to try the collectible card box idea, which I'd been considering for a while.
There are many different sizes of collectible card boxes. There are boxes that are about half the length of the box up above, although I've only seen those online. There are also larger boxes that have three or four rows inside for cards. Of course, the boxes, or slots in a larger box, are only one general width, collectible card width. However, that seems to work out really well for things like Barbie-sized shirts and shorts/shorter skirts. Plus, when they are standing upright, I can flip through them, almost like cards. It's not like in a box where they are laying flat, when you might have to pull a bunch out to get to the ones in the middle. At least, that's what I ended up doing. :)
Slightly longer skirts fit in fine sideways.
I've discovered that the length of the boxes that I have, is perfect for knee-length dresses and longer skirts, and pants/capris.
I tried out the next size box, to see what I could fit. For now, this is going to be both my "ankle length, poofy skirt" box, and my full-length dress box. Since the box is really too long for either, I'm kind of sticking the skirts at one end and the dresses at the other, for now.
Of course, there other lengths, and I may be able to find something a little shorter, length-wise, online. I bought these from our local gaming store, because Mr. BTEG and the Dancer have played games there for hours on end, and I want to support the store. Now that I think this is going to work well, I can experiment with other sizes, too.
Just to share my experience with you, what went wrong with the 3-ring binder method was that I only wanted to use the smallest plastic pouches for my smallest tops, to save space. However, because of the thickness of Barbie clothes that I mentioned earlier, the tops really wanted to just pop right out of those small pouches. On top of that, I quickly filled up two binders (with more clothes than you see here) and both binders were so stuffed that they were too fat to hold their neat triangle shape. I could easily see the binders getting out of control, space wise, plus some clothes were falling out of the pouches, and putting them in a sleeve with bigger pouches would just take up even more room.
Teresa organizes hers in plastic bags, and then in larger plastic bags, by things like doll, year, and what fashion pack it came from. However, I'm not really much of a collector when it comes to Barbie clothes. I don't try to collect all the outfits and accessories from the 1965 Barbie and Ken wedding set (making the name and date up here.) I'd rather be able to find them by top or knee-length dress, rather than what Fashion Fever multi-outfit pack it came from. We take different approaches to our fashion doll clothes, which is fine. I hope maybe my approach will work for one or two of you out there.
I also have outside box measurements, if you are interested in those. I'm not sure how these card boxes are officially measured, if it's from the inside, or what. But this should help you know what you're looking at, when shopping for your own boxes.
Length: 7.5 inches, about 18.5cm
Width: 4 inches, about 10cm
Height: 2 and 7/8 inches, about 7cm
Length: about 12.5 inches, about 31cm
Same width and height
If you prefer plastic boxes and can find some in a useful size, great. When I decided to try the "standing up" approach, the only thing I could really find both narrow in width and long enough in length were collectible card boxes. Obviously, they're not going to set inside each other for stacking, like some plastic boxes will. But, they do stack, and maybe in the doll space you have, you'll store them all flat on a shelf or in something like a drawer instead. Anyway, this is a storage approach that I have not seen anyplace else, and I hope if it doesn't work for you, it might spark an idea for something that will. Happy storage!
