Ready To Seam--please advise!

Woo!
I’m about to do the side seams on my first ever garment (it’s a sweater vest). I’d love some preparatory advice!

Do I just mattress stitch these babies up, or do you recommend another method? How do I keep things neat and orderly?

Should I pin the pieces together to keep them even, would that even work?

Should I start at the armpit and work my way down or start at the bottom and work up to the pit?

:shrug:
Thanks in advance!

Definitely mattress stitch.

What you can do if you’re nervous is to match up the top, bottom and middle just to make sure you’re staying on track. I guess you could pin, but I usually tie yarn to attach the sides, mainly because it’s right there.

I always work from the bottom up so if there is a bit that isn’t even it ends up in the armpit.

Ingrid to the rescue, right on cue!
Thanks so much! :muah:
