While waiting for Procreate to develop a dedicated pattern preview, thank you so much for these tricks and tips! Your website's Repeat Pattern Tester is also very user-friendly. Thanks a lot!

I used this half-drop pattern that I created previously in Procreate to test the Super Zoom to avoid the white lines, as well as your pattern tester preview. The second pattern with the "cashews" shapes was an experiment to work on the preview trick.
