Welcome Back
Since this month’s Virtual Crafting Challenge is paper, I thought you might like some tips on how to store your ever grown paper and card stash.
Moisture and light are the enemies of card and paper. Avoid them if you can, either by storing your card in solid colour boxes so the light cannot get through. Alternatively put your clear boxes in a dark cupboard 
I would strongly avoid using card board boxes to store you card and paper stash in for long-term storage. You may have bought scrapbook safe papers but if you store them in acid rich corrugated card boxes, they will become discoloured by the storage boxes acid and lignin!
My favorite option for paper and card storage are the Really Useful Boxes.
Really Useful Boxes for storing Paper & Card
The Really Useful Boxes are really sturdy, strong and have clip down lids. You want to store these in a cupboard though as the clear plastic means if they were stored in direct light, the papers inside will still fade over time. The boxes are available in a wide range of sizes, from stores such as WHSmiths, Staples and Hobby Craft. Try office supply stores too.
Less bulky are these kind of boxes. (Haven’t seen a brand name on these, sorry).
Plastic Box for storing Paper & Card
These are great and still stack but because the lids just drop on, unless you pick them up just right, you can easily drop the contents out by mistake! Also available from Hobby Craft.

I bought a whole stash of these (second photo) last year (when I still had a job!) at the NEC. Not the easiest things to carry around a show with you either
Not only are they great for storing card and paper to keep them dust free and flat but I also store pens, pencils, markers, ribbon, dew drop inkpads and some embellishments. I bought 12 x 12″, A5 and A4 size boxes and could do with a few more! Our young granddaughter has an A4 box at our house with some craft supplies in too as she loves to craft with me.
I just love these boxes as not only are they inexpensive but deep and stack so hold masses of items and the contents can be seen through the sides. All the ones holding cardstock have been labelled on the end so that when I open the cupboard I can see quickly which box is holding the cs I need.

Hi Lynn
They are great and as you say stack well. I am clumsy though, so the security of the click on lids makes the Really Useful boxes my faves
