The Silhouette hook is an essential tool for removing excess vinyl from around your cut design so that it does not transfer onto your garment. Once you have cut your lettering or design, cut design out into a smaller portion, then using the hook tool remove vinyl surrounding your design so your graphic is now read to be heat transferred. This design will then be placed upside down for heat application. This hook tool makes this process much quicker and reduces risk of damage to your design.
