Work on sunday: Art, writing, and more to earn cash

Is it wrong for someone to do such things like writing original fiction to sell on amazon later on a sunday? What about sewing or crocheting an item to sell later?
Painting an image to later sell?

For people who make small cash on the side and also people who make a living doing such things is it wrong?
I appreciate any answers . :slightly_smiling_face:

I have earned small money on amazon for writing fiction.
