Annie's Keepers tells us: "Storage Pack includes approximately 300 Annie's Thread Keepers with labels and 20 Storage Slides with hooks. 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 Storage Slides. Each Annie's Thread Keeper has a ridge that allows it to slide into the Storage Slides and stay securely. Each Storage Slide will hold 16 Annie's Thread Keepers. To remove an Annie's Thread Keeper from a Slide, simply twist it slightly to open the Slide and pull the Keeper out gently. There is no need to remove several Keepers to access one in the middle of the Slide. The Storage Slides have hooks on the ends and will hang nicely in a standard file drawer or file box.
