Being a designer and crafter, I have to have a lot of sewing things like zippers, buttons, thread, needles etc and in order to not have to spend hours looking for what I need, I have everything pretty neatly organised. It might take some time and effort fixing everything and getting it the way you want it, but I can’t tell you how nice it is to have what you need so easy to reach.
I use these plastic boxes from IKEA, they are pretty cheap and they come in a variety of sizes. I have bigger ones for fabric. I put labels on them so that I can easily find what I am looking for.
ps! some of the vintage zippers are for sale here!
