Just a bit of trivia....in Aus. a serger is called an overlocker.

There is no such thing as a stupid question. Glad you got you answer.

So what would one use a serger for in quilting?

I ask because I have several quilting friends who talk about using their serger all the time but I can't imagine what for. I guess I should ask them; I just never have.

I have seen quilt blocks put together with a serger. They made an adjustment to the seams, and then sewed them together without using the cutting blade. They tugged on them and then the seams kind of "open up" so that they layed flat. It gave a decorative look to the seam lines, as you could see the thread, it kind of looks like a narrow sashing.
It is also a nice way to finish the edges of quilts before you turn them, using the birthing/pillowcase methods.

Please feel free to ask any questions here :D:D:D

I saw a show on TV the other day about decorative stitches done with a serger. It was amazing. I had no idea they did anything except finish a seam. You learn something new every day.
