きらいとすきとじゃない (kirai, suki and janai)

Hi! I am hitting a wall with my Japanese studies. I know all Hiragana and Katakana. I have been studying for a long time on my own. However, I am getting kind of confused on how to use janai with liking or disliking something! Can I get a few sentence examples/explanations? 

Also, I am looking for life long friends who can speak Japanese! Teach me Japanese, I teach you English! Thanks so much!! :D

よろしくおねがいします！
