I have several of those big plastic three drawer things and they are full. Red in one drawer, etc. Then I also have a thread rack for what I am currently using, and what I have not put back yet. Then I have all my embroidery thread, (machine stuff) in special clear containers. Well, that is the small sizes, the bigger ones are in another drawer thing. Then all my serger thread is in a big dresser drawer.
And guess what, I really need to buy actual cotton quilting thread. I have been trying to use what I have and not buy more, but I have mostly blends so I guess I should buy more. Is that crazy or what?
