As a Zentangle artist, one of my favourite tools is a tortillon, that is used for blending graphite for smooth shading. But what do you do when the tip becomes worn and rounded? How do you recover the nice sharp tip that lets you work fine detail?
Cindy Angiel (rainbowelephant.com) shared a great tip. Here is a tortillon with a worn tip, and a straightened paperclip.
Insert the straight end of the paperclip in the top of the tortillon and push. This pushes out some of the paper in the middle of the tortillion and refreshes the tip.
Is this cool, or what?
