Если это письмо в начале в правом углу напиши город, страну и дату. С красной строки слева пиши I was glad to receive your letter. How are you? I'm fine/ ( я рада получить твое письмо, как дела, у меня все норм, это вводная фраза) Основная часть: In your  letter, you asked about me. As for me, I collect different postcards. I have 40 cards. I buy them in stores, when travelling or as a gift. I also like to draw. It's my hobby. I can draw very well because I've been doing this since childhood. My drawings very much, for example, still lifes, portraits, landscapes and my ideas. As for my parents, my mom likes to do handmaiden and she does it very well. She participates in exhibitions of needlework and her works are bought by people. My dad loves computer games. We also play with him and sometimes I win. ( начиная от жирного шрифта это заключающая фраза, ее пишишь с красной строки)THAT'S all for now. Keep in touch. Hug you.( Hug you на следующей красной строке и под ним свое имя и без точке в конце) Удачи, чувачек
