"In this tutorial, I’ll explain how to make custom spirals (apart from the default spiral tool), and use them creatively in making rolls of paper. So far, I came to know that the spiral tool does not allow a uniform decay (equal spacing) between each wind of a spiral. In this tutorial, I will expose some basic tricks to do so. Hope you find it interesting." - Saurabh Sharma
