I'm sorry. I can't make this work !!
Working on the same baby sweater--"babies who lunch" in Sublime yarn. This is a cardigan with raglan sleeves. Under the arm there is a 5 stitch bind off in one row, so it is horizontal. Then the rest is slanting decreases. It never is perfectly horizontal/vertical, and it never is right for mattress stitch according to the video under "finishing". Sometimes the sleeve stitch is slight vertical and sometimes nearly completely horizontal. How do you make this work when trying to join the sleeve to the body?
Thank you again.
