I’ve added a sandbox catalog.
It’s a test catalog filled with sandwich data — sandwiches, servings, and chefs — that you can use to try out ctlgs features without worrying about messing anything up. Add entries, edit things, build a collection, experiment with the forms, whatever you want.
The sandbox resets periodically, so nothing in it is permanent.
It’s a good place to get familiar with how ctlgs works before contributing to books or gigposters.
