I use lots of these suggestions.
I like the envelope one and buy old 3 X 5 card file boxes from second hand stores. Have one for "Resistors" , "1% Resistors", one for "high volt caps" etc...
Works well for thru hole devices.
I like the smd sampler approach also. I make my own clear plastic sheets using a crafting method. You can make any size pocket in a cheap plastic "protector" Works well for loose leaf sheet size units and make the pockets any size you want. It is just a soldering iron with a roller tip.
