Help! Organization issues!

Can anyone give me some tips on how to organize penpal stuff? I need to figure out how to save letters, stationary, stickers, pens, and basically all the materials! i can't seem to come up with anything other than all my notepads and a few pens stuffed into a shoe box! At the moment, I have all my letters put in the bottom drawer of a plastic set of drawers. And also, I need some bedroom re-organizing help! I'll be getting a few new fish tanks, some small betta tanks as well as 2-3 tanks the size of the goldfish tank. here are current photos:
