Tie a pen to the end of a thread wound clockwise around a spool. Pull the thread taut and move the pen counterclockwise to unwind the thread. The pen traces a curve approximated by an Archimedean spiral: The distance from the pen to the center of the spool is nearly proportional to the change in angle made by the thread relative to horizontal.
Made entirely from recycled plastic bottles and stretched over a lightweight, recycled frame, our custom eco canvases are a great way to introduce some sustainable art to your online store – even the packaging is made from 100% recycled content! Better yet, they’re almost half the weight of traditional wooden canvases and cheaper, too.
