Somewhere I heard or read a tip about pipe cleaners for thread/bobbin storage long ago. I've searched for hours in my sewing books and on PR in order to give that peson credit but I can't locate it. I've expanded on that idea by using shallow boxes for storage and sorting the threads/bobbins by colors
This is such a great idea and stress reliever so I am adding it now because it deserves attention.
One thing that aggravates me with sewing is finding the bobbin that matches the color or type of thread on a spool. This problem compounds when you have multiple SM's which use different sizes of bobbins. So to keep spools and bobbins together you simply insert a pipe cleaner through the spool of thread and bobbin(s) and bend the end of the pipe cleaner over the ends. This holds them together. The pipe cleaners can be snipped to shorten to fit your needs. Pipe cleaners are so inexpensive too--much cheaper than all the other notions they sell to keep bobbins with thread spools! And another great benefit is that if your thread label comes lose, it stays with the spool and bobbins so you always know what kind of thread it is!
I use shallow boxes and sort my threads by colors. Using shallow boxes keeps it all easy to see what you have and because you can see it all you don't have to dig around to find what you want--therefore you don't get all the tangled mess.
So to whoever you are that I heard about pipe cleaners from I thank you from the bottom of my heart! I have had my threads like this for at least a year and I love this system! No more aggravation!
FYI: I bought the pipe cleaners at JoAnn's. I bought white but they come in colors too.
