Dear [Recipient],

I hope this letter finds you well. I wanted to share with you my favorite hobby, which is painting. I enjoy painting as it allows me to express my creativity and emotions. I usually paint at least once a week, but whenever I have free time, I try to indulge in this hobby. Sometimes, I also paint with my friends, which makes the experience even more enjoyable. Painting helps me relax and brings me a sense of satisfaction when I see the final result. It is truly a therapeutic activity for me.

Best regards,
[Your Name]
