Abstract: A computer-implemented method for creating a digital canvas for printing on a foldable medium enables a user to create custom designed folded objects, such as custom designed origami envelopes. The method involves receiving a specification and a user input, and placing an image at a desired location within the digital canvas based on the specification and the user input. The specification comprises a first data set describing an intermediate configuration of the folded object and a second data set describing a folded configuration of the folded object. The user input defines a position and/or an orientation of the image in at least one of the intermediate configuration and the folded configuration.
