i really like the thought of making separate kits for different things. one for sewing, one for first aid, one for fire starting. these tins are small enough that you could have a bunch in your glove box.
Wedding Day Emergency Kit - need to remember to get all this so I'm all ready for my maid of honor duties! Also, need to add a Mr. Clean magic eraser to this list! Best thing ever for removing stains on delicate fabric.
