feltlogg

Feltlogg is a term used in textile arts to describe a structured record-keeping practice for feltmaking projects. The word blends felt, the fabric produced by matting fibers, with logg, a spelling variant of log used in some Nordic languages, and has appeared in craft blogs and online forums to describe documentation workflows for felting experiments.

A feltlogg typically records materials, methods, and outcomes of felting work. Common entries include wool types (and blends), preparation steps, felting technique (wet felting, needle felting, or nuno felting), water temperature, agitation, duration, humidity, and any additives. It also tracks tools used, final dimensions or thickness, density estimates, colorfastness, and notes on the finished appearance. The purpose is to enable reproducibility, support quality control, and facilitate learning from previous attempts, as well as to share procedures with others.

History and usage: The term emerged in maker and artist communities during the 2010s and 2020s as practitioners sought a consistent way to document experimental outcomes. Feltlogs can be kept as physical notebooks or as structured digital records, including photographs, sketches, or diagrams, to supplement written notes and enhance communicability.
