A Medieval Bat patch for your jacket, vest, shirt, backpack, or bag. It will come rectangular-ish in shape. It features a derpy little bat with fangs. Sew it on however you want. Use a fray glue on the edges if you don't want any fraying.
This is an affordable cotton fabric sew-on patch
I use either white or black sturdy cotton (whatever is around). Please note that some fraying is expected, and the fraying could be white or have some white in it. Don't like the white fraying? You can color it with a marker, paint, or dye.
