In the woods, trees grow slowly, making annular rings and new branches that mark the passing of time. When harvested, their trunks are stacked to dry. The cut ends weather and create the circular patterns of dark disks familiar to us on woodland walks. The wood industry discards these ends, but Tina Astrup collects them and takes their history into her designs.

By wrapping metal thread around oak tree and pouring vinegar over it, Tina Astrup draws either fuzzy or crisp lines in the wood, using a chemical reaction.
