When storing crafts, you want to be careful, not to store them where they might get dusty, damaged or cook; some carfts may be stored in a cool, dry place, others can be stored in boxes, storage containers & such.  But be forwarned, there might be sunlight coming through & if you have clay of 1 form or another, you might have to store them in a closet or somewhere away from sunlight; also, if you have beads, cloth or scrapbooking supplies, then make sure you store them in a container, for sunlight not to fade them or make them so hot, they melt or fray.  Also, when storing them, try different places, the if you're planning on moving them & you know they're gonna be in some sunlight, make sure they're covered or somehow protected from the sun, unless of course, they're clay, then you may have to store them in you may have to store them in a cool dry place, away from sunlight. 

When storing beads, you want to be extra careful as to not allow sunlight to hit them, or have them in the sun for long periods of time, or they will fade; the same goes for storing scrapbooking paper & other crafts you don't wish to fade.  If you have stickers, die cuts or any photos, you may also want to do the same thing & store them in the same manner as your polymer clay, beads & scapbooking paper.

Any other crafts can get heated by the sun, but won't cook (like clay), or fade (see above), but instead will fray (cloth) or just get too hot to touch; be very careful when storing them, however, as you don't want to stack them so high, that either it'll become a fire hazard, or you can't get to them when you want them.  If you're like me, you like being able to get to all your crafts easily; well the best way to do this, is to see how much room you have & go from there.  Also, you may want to start getting rid of any crafts you don't use, need or want, that will cut it down some; then decide how you want to store them, where you'd like to store them & how easy it is for you to get to your crafts.  1 you do that, then you're set & ready to start crafting.
