Hansje van Halem creates alphabets, textures, and patterns both digitally and manually and applies them in designs for posters, illustrations, and public space art works such as gates and floors. She continuously keeps track of the unfinished sketches, type drawings, motifs, and expertiments, whether commissioned, applied, self-generated, or rejected. It is a dizzying array of successes and failures, both used and unused, as unused material often becomes a source from which Hansje draws further inspiration. Parts of this material were published in Sketchbook (2013) and Sketch Cahier (2014).
