If you were to ask me my favorite notion, I just might say my hera marker. It changed the way I mark things for the better, and it's always nearby. But you know another one I really like? A bodkin. It's not something I use in my quilting, nor most of my sewing at all. But when I make something with a casing, I am so, so thankful for my bodkin. After years of using a safety pin to weave ribbons and cords and such through casings, I discovered the bodkin, and it makes things SO much easier and faster.
By definition, a bodkin is "a blunt, thick needle with a large eye used especially for drawing tape or cord through a hem." Mine is just a long flexible plastic 'needle,' but whatever, it works so well! A task I used to dread is easy peasy now.
