How can I keep LEGO winches from becoming tangled? I have some LEGO winches/strings with hooks.



Putting these away inevitably results in tangled strings (the next time I take them out). Even winding them up doesn't help.

Storing these in drawers and/or shelves is not an option for me. I keep most of my LEGO collection in a LEGO Star Wars box.

Is there some way I could build other bricks onto these so they won't unwind?
I take 2 of these: 

Place 2 pins in the holes 

And then sandwich the loop of string between.

It works well and you likely have the pieces lying nearby.
