I keep an expandable file folder to store all my findings in. I saw this on a video somewhere, but I can't remember where.
Inside, I label the tabs in alphabetical order what I have in each slot.
In each slot I have a gallon ziploc bag that hold everything in that category and I also label the bag. This makes it easy to find every time. You might be wondering why I use such big bags, because I can hold everything in a smaller bag. I use gallon size ziploc bags because it's just easier to grab.
And that's about it. Keeping everything this way makes it much easier to find things. I know it's probably not the best way to do things, but I use the resources I have on hand.
So, here's the tip for today: Label EVERYTHING. Right now I don't have everything labeled because when I first started beading I didn't label anything. I didn't keep receipts because it was just a hobby. Now I keep all my receipts and I label everything. If you are unsure how much information to put on your bag, then just put everything on. I'm not kidding. More information is better than not enough.
