I think you would enjoy painting more than crochet !!
Best thing is to go to a Op Shop or Library and get a learn to draw book. Not learn to paint.
Then draw something in light pencil. Then paint in your drawing making sure to hide the out lines.
After about 6 of these, paint only and you will be surprised at your advancement.
You can buy paints / sKetch books cheaply at dollar type shops and also buy some oil pastels. These are great for learning as you can shadow...alter.. by smudging / shading.. with your finger.
Art is not a given talent....its like anything done well ...PRACTICE....then you will evolve a style of your own!
I taught my daughter the same way and now she is in demand in Brisbane for her wonderful murals in many restaurants etc .. see pic. She just finished this for a Mexican place... You don't need luck just perseverance and appreciation of your love of art. Cheers. Peter
