Knitting

Recently, i had came out an idea just to cheer someone .I was thinking to knit a sweater (Nothing much, juz want to show some caring). When come to knitting, i was totally out of idea as i don't even know how to sew. (How can I knit a sweater?) Well, i had done some research before i start knitting. It is kind of hard, but i still insist to do it because i do it for someone that i really care! However, i did change my idea at last (dont wan to knit) as i dunno it is worth for me to do all this kniting stuff?
