Please test the new Background Maker on CoaMaker (free and Pro)!
It allows you to
add stripes, bars, and diagonals,
change the line style of stripes, bars, diagonals,
add crosses, determine their intersection, and add cross layers (like the Norwegian flag),
add bends, determine their width, add more layers of bends,
add a bordure.
You can layer the different types of pattern by making parts of them transparent.
All patterns adjust when you change the canvas ratio in the background editor.
You can keep editing your current background-style until you save and open it again. In that case, the pattern layer loses its ability to be edited with the background editor.
The background logic is very complex. Let me know if something is broken and how we can improve the interface and the workflow
