@skye you should be able to use the same technique on the middle seam? Oh, wait, I get what you're saying now. Lol

A serger is a special kind of sewing machine that sews a wide seam using a whole lot of thread! If I understand how they work right, they kinda crochet the thread together around the seam.

If you have a shirt made of a knit material (like most t shirts), you might notice that the seams have a whole lot of thread on them. That's made using a serger, and the benefit of it is that the seams are more stretchy than using a normal sewing machine stitch.
