Stylish Borders using Quick Mask Mode » Pixelmatortutorials.net
This is the front page of PixelmatorTutorials.net, a long-running tutorial site for the Mac image editor Pixelmator that claims over a thousand daily visitors plus podcast downloads through iTunes. It features two recent posts: a video tutorial from April 2016, after a months-long gap, on using a map as a tattoo-like image on a hand (with layer masks, overlay and soft light blending, dodge and burn, and pinch distortion), and an October 2015 PDF text tutorial on building a textured collage from layers and blend modes. Worth keeping mainly as a pointer to this specific Pixelmator learning resource and those two techniques.
