I find a crochet hook with a tiny hook a very versatile tool. I use it to get new spool thread started. I use it to tear out seams by sliding the hook under the stitched thread and pulling it out, then I have a tail that I can pull. (I tend to get a little rambunctious with a seam ripper and routinely end up gouging the fabric.) I use the crochet hook to pull the threads out from under the presser foot after threading the needle....
