I have finally managed to sort all my thread, using the system from Lostincrossstitch. It took ages (well, months in total) and I'm really happy it's done! I like the system, it's compact and I can easily access everything. My (paper) inventory is up-to-date too! There are a few full skeins (lots of black) that didn't fit and are in photo boxes (an idea I sto--borrowed from this sub).
