(Bonus tip) Now, I already mark my tags on the wire for easier identification, all the necessary info in on the back of the tag, in permanent marker. For example: FS - fine silver; SS - sterling silver; gauge; round; square; HH - half hard... you get my point. So if I have a bunch of wire on my bench, I can easily see what I'm looking for and frankly, the info from the manufacturer is very small and my eyesight isn't what it used to be.
Then, loaded into the expandable file folder, each slot marked with gauge. Each group of wire marked with easily seen identifying information. Added bonus, it is super portable and I can take it anywhere with me.
