I’m working on a muslin with hopes of eventually finishing several blouses using Vogue pattern 7903. I always have to alter the pattern using a square shoulder adjustment.
To begin with, I’ve slashed the front and back pieces from the armhole edge, beginning about 2 inches below the seam allowance for the shoulder seam and to where the shoulder and neckline meet without going into the seamline. My first question is, do each the front and the back need to be slashed equally? I’ve opened them both up about 1.5 inches.
Next question–at what point of my shoulder does the shoulder seam need to meet the top of the sleeve? The muslin shoulder seam looks okay at the neckline but as it reaches the sleeve/armhole seam, it looks like it’s a little “back”. That, I’m guessing, may be related to my first question. Also, I now have over 1 inch of fabric, maybe even up to 1.5 inches of fabric of the shoulder seam hanging over my shoulder onto the top of my arm. This extra fabric gradually decreases approaching the side seam to join the front and back. I have a French curve. My question is, how do I draw a new armscye?
Also, does the top of the sleeve need to be slashed the same amount as the front or back? What I mean is to slash near the top of the sleeve cap perpendicular to the grainline 1.5 inches across so the total changes made equal that of the bodice front and back changes combined.
I’m looking forward to some assistance.
Thank you very much.
