A sew-on embroidered fabric patch, made with scrap fabric and washed and recovered single-use plastic backing. The Pumping Station:One symbol and edge stitch are standard but the fabric base makes each patch one-of-a-kind.

Heirloom patches are shipped without iron-on backing glue to encourage re-use when clothing or fashion changes.

Profits go to Pumping Station:One, a 501c3 non-profit hackerspace in Chicago, USA.
