I love all of those ideas! I wish I knew how to sew.
I saw a neat idea once for old/torn/messed up ties - you'd cut the end off and sew it all up, add a button hole, and you could use it to hold your mp3 player or glasses, etc.
I re-use the small tins of veggie pastes/plant spreads, you know those with a plastic lid, to store paper-clips, buttons and other small stuff. Usually I stick some paper with nice motives on them - but those fabrics are really cute!
