You’ve done everything right so far, to start testing go to the regular ribblr homepage, then click the tab labeled “my stuff“, click your username and go to the drop-down menu and select testing. This will show the patterns you have been approved to start testing.
When the pattern is ready to be tested, go to your shop, select the pattern, and click the Testing (clipboard) icon. Choose “Post a tester call” to create a community post detailing your requirements, deadline, and materials.
