How do I attach small wefs of hair extensions?

I want to put in a few small pieces of wefs (Hair extensions) I attached some to extenion clips, but my hair is pretty fine and the clips don't stay in too well. At least, they will come out if I pull on them. I don't know how to cornrow and I don't know anyone who does. And really, the wefs are only 2 inches wide. So I guess what I want to know is should I just glue them, or is there another way to sew them without making a cornrow?How do I attach small wefs of hair extensions?
