It also depends what I am quilting. If it is a utiity or charity quilt, I will often just take the tiny little stitches and clip. If I am quilting for others, or if it is something like feathers I will pull my ends into the middle of the quilt. I don't use a crochet hook for my thread ends, but I do know many longarm quilters who use this small hook to fix mistakes that you cannot get to any other way.
