Made from cotton scraps. These patches have an iron-on adhesive back. We recommend sewing the patches down for optimal durability. Note: All patches are one of a kind, photos show examples, not inventory available. You can request color families and we will do our best to accommodate you if it's available. Some patches will be the mirrored opposite. Each patch comes packaged in a compostable sleeve with instruction sheet. Also available with no packaging on request (please specify whether you still want the instruction sheet).
