As with most motifs I draw, I redrew the cat several times. I used a photo (not having an actual cat anymore) and made several very different drawings from the same source photo.
So, I guess we’d have to call them “mistakes” given that they do not accurately reproduce the photo. But I love my “mistakes” — they turn one cat into several, each with a different mood.
Cherish your mistakes, artists, and be sure to make as many of them as you can! Il faut refaire la même chose dix fois cents fois. [You must redo the same thing ten times a hundred times.] Mr. Degas said it! And we must do it!
