please ignore my children screaming in the back they're not having a get a long day I just thought this video might be helpful to show how to sew corners with a serger I just finished one edge and I'm at the center of a seam where you should with the regular sewing machine you put your needles down and then you pivot the fabric with a surgery you can't do that though it really is only made two so in a straight line so what you were doing instead so you can see the fabric wants to pull to the right is you would pull the fabric out straight and you would line it up and continue so cut your thread and what you will have now I can lay this out with my hand so now you can see that there is a nice little angle to the seam this is actually the crotch and a pair of shorts so hopefully that's helpful
