Practice signing a legible signature on a piece of paper. Then, show a few friends and ask if they can read it. If they can’t, work on making it easier to read.
For example, if your painting features a bowl of apples, you could place your signature inside one of the apples and paint it a shade of red so it blends in.
For example, if you used watercolor paints to make your painting, you should use watercolor paints to sign your signature. If you made your painting with oil paints, you wouldn’t want to paint your signature with acrylic paint.
You can abbreviate the year if you want. For example, instead of signing “2017,” you could just put “17. ”
