Perfect for pre-cut lengths of thread, 3" long x 2" wide...with a space to write the number or the project. If you have longer lengths, simply cut you own into your desired length and pop the halfway point through the larger hole. Use a keyring to connect muliple thread hangers so you can take your project with you wherever you go.
We also have the die so you can make your own if you wish. It is die 8001, You get a mat included with each of our dies, but for the Sizzix, you need an extra 2 mats to get the correct height.
