Patch is made by me, not industrially produced, so small variations may occur. Edges are sealed. Back options are: sew on patch (no backing), iron on patch (heat backing, only for materials that can withstand heat), and adhesive backed patch (adhesive is meant to be permanent and may leave behind residue if removed). For the strongest attachment, sewing is recommended regardless of the backing chosen. Sew-on patches can also be glued in place.
Patch can be made with a felt or standard base. The felt option offers a softer, more noticeable black edge, while the standard base has a more discreet sealed edge that results in a harder edge. All backing options can be chosen with either base.
