It occurred to me that it's very easy to reverse images using GIMP. In 2D, it's reflection about an axis and GIMP provides rotation about the vertical and horizontal axes of a picture as predefined operations. Reflection about an axis in 2D corresponds to rotation about an axis by 180° in 3D.
I now have right- and left-handed versions of this drawing and also of the ladybug fairy. Handed-ness or parity is an interesting mathematical topic and it can be used for interesting and sometimes confusing or puzzling visual effects.
Using the upside-down images also makes it possible for me to use the space on the page more efficiently. Making these cut-outs is producing even more scraps of paper than usual.
