Seaming on sweater arms?

:XX: How do you seam the arms if they have decreases and increases? Its hard to tell where to do the mattress stitch on the decreases and increases… :thinking: AmyC

It is hard. I usually try to go in one stitch in from the edge as best I can.

It also helps if you don’t do the decreases/increases right at the edge. Even if pattern say to, I always do the inc/dec two stitches from the edge, then you usually have a nice clean line of plain stitches for seaming along the edge. I agree though, seaming in sleeves can be challenging at the best of times.
