Seaming Sleeves Help!

Ok y’all know im making Debbie Bliss’ Ribbed baby jacket. So Im now seaming. Doe the sides quite well, but oddly enough Im having trouble seaming the sleeves part.

Im using mattress stitch, seaming on WS. but oddly enough after doing the sleeves it looks like I seamed on RS…thats not right…
.
am I doing something wrong? is there a diff method Im suppose to use? Help

I can’t say that what you’ve done is necessarily wrong, but if I remember correctly, mattress stitch is worked on the RS…

I agree. Definitely fromt the RS unless you want the seams to show. It can be a little tricky unless you’ve made your increases one stitch in from the edges on the sleeves.
I hope we get to see this adorable sweater?

If I ever finish it up - yes. lol. not having fun right.now
