6" screw fastener ring for holding Annie's Thread Keepers. See related products below. Annie's Thread Keepers are a comprehensive system of floss and fiber management. Simply cut thread to desired working length and insert it in the bottom hole of the sturdy acrylic 3/4" x 1-7/8" Annie's Thread Keeper. A loose knot will hold the floss securely in the Annie's Thread Keeper yet allow you to pull out your next strand without unknotting the thread. Use the round adhesive label to write the color number and stick it on the space above the hole. When you are working on a particular project, you may also draw the color symbol for that pattern on the label. Place your filled Annie's Thread Keepers on either a 3" Project Ring, or a 6" Storage Ring, or in Project Slides or Storage Slides.
