Leftover yarn / fabric scraps / cardboard scraps / scraps of all kinds

Dear users, dear authors,
How many leftover yarn scraps / fabric scraps / cardboard scraps / paper scraps / scraps of all kinds do you currently have, and what do you do with them?

I still have a cardboard box full of acrylic yarn, but I won’t know until the end of the year which of it is leftover and whether I had to buy more, since that’s going to be the temperature blanket.
Then there’s a large box of leftover cotton yarn and a few full skeins that I’m gradually crocheting up as I work through the patterns I bought here.
There are also two nice (different) Bobbel yarn cakes left; I’ll have to see what each one is enough for or what else I can pair them with.
I used to have several boxes full of fabric, but I cleaned that out and got rid of some of it. Now I only have fabrics left that I know what I want to make with them someday. I’ll check them once a year to see what never gets made after all—or what does.
I don’t have much else—just a few different ribbons, beads, wire, and charms—which I use every now and then to make a bag charm or keychain; those always make nice little gifts.

I have almost nothing but scraps (= partially used skeins). And new ones keep piling up because I don’t skimp on buying yarn for larger projects—I hate it when I run out of yarn at the end.  And what do I do with the scraps? I keep making new little projects! It’s no coincidence that my shop’s motto is “Crocheting with Leftover Yarn.”
However, there’s always a lot left over...

At this point, I have almost nothing but scraps and single skeins. I’m currently making a slipover out of two scraps; I’d like to crochet the cotton scraps, and the acrylic scraps will be donated soon. Then there’s still quite a bit of sock yarn and various skeins. Once everything is used up, I’ll buy some new yarn.
