Screencasters Episode 068: Halftones
In this episode I will show you how to make halftones in Inkscape v0.46.
I used istarlome’s diviantART tutorial in order to learn how to make halftones. Also, Ryan Lerch posted a link to a Sidux tutorial on tiled clones as well. I thank all three of them for teaching me so that I could teach you.
