A Medieval Bat patch for your jacket, vest, shirt, backpack, or bag. It will come rectangular and features a flying bat.
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.
