the "corrections" are a series of wall drawings based on a collection of notes taken from different persons. these include for example to-do-lists, drafts or shopping lists - all of them spontaneous expression which are not meant to last long. the focus of this series is on cancellation marks in the notes. a note is picked due to the proportions of the wall. the cancellation is then isolated from the rest of the noted information and transferred to the wall by hand as accurate as possible.
