Chambers is one of the textiles that was kept undersoil for a period of time in an empty plot for the project Groundworks. L'Hospitalet de Llobregat (see Groundworks. L'Hospitalet de Llobregat in Works 2015-2019). The fabric was buried with a series of objects on top of it, that left big marks on its surface, when unearthed. The organic components in the soil and the temperature variations during two months, made a "drawing" of their own on the fabric. This “accidental” drawing was partially re-drawn by erasing some parts with bleach and completing others with graphite pencil.
