If the patterns are wonky, you can go into your Tailor Tales Folder, and browse to: Tailor Tales/www
In that folder should be a file called package-NoWebGL.json and a file called package.json. Rename the file package.json to something else, like package-old.json. And rename package-NoWebGL.json to package.json so that the game uses this file instead. Then reload the game.
Hopefully this should make patterns appear for you.
