You can attach as many canvases as you like to cards on Task Boards or Scrum Boards, and if you don’t need them anymore, you can delete the canvases.

Here’s how you add a canvas to a card:

By default, the new canvas is simply called “Canvas”, but like with any other attachments on a card, you can easily rename it by clicking on the pencil icon that appears to the right when you hover your mouse over it:

Clicking on the “x” button at the far end will let you delete a canvas that you no longer need:

If the canvas is empty — which means that there is nothing visible on the canvas, and nothing in the canvas’ Trash either — you see a simple confirmation message asking if you are sure you want to delete it:

But, if the canvas is not empty, you see a Restore option instead:

If it seems puzzling why a canvas that appears empty isn’t really empty, make sure you open the canvas and take a look at the Trash: there may be items there that you had previously removed from the canvas:

In this example, above, the canvas looks empty but isn’t really: there are items in the Trash.

In situations like this, Kerika is careful to avoid losing all your work: until you empty the Trash on a canvas, the canvas isn’t considered to be truly empty, and until a canvas is truly empty, it cannot be removed from a card.

So, in this example, you see the Restore option rather than the Delete option:
