When you're first starting out in electronics, chances are you bought a resistor assorted set and you dont have any place to put it in.
So for my way of organizing my resistors is by using coin envelopes and a printed label on a sticker for easier identification.
As you can see, I've also added a marker so that I can easily find the #of the resistor.
It's grouped by the 1st number (i.e. 1, 10, 150... etc. )
