Teresa asked, “My dog knocked over my cup of coffee and soaked my new ball of thread. What can I do short of throwing it away?”
Thread cleans just like any other fabric. You can try your regular spot remover, or vinegar and lemon, or whatever you would normally use to clean clothes. Whatever you try, however, I suggest trying it out on a small piece before doing the rest, just in case it doesn’t work or makes it look worse.
Another option is to bleach and then die the entire thread a new color, and hide the staying that way.
Any other suggestions? What has worked for you?
