Plain frock or an” A” line frock draft can be converted to one shoulder frock. Neck and arm hole is stitched with fitted facing. Interfacing can be sandwiched between the bodice and the facing to keep the shape of the bodice. We can also prepare a casing along the neck line and pass elastic through to keep the neck line in position. In place of the other shoulder spaghetti straps can be used as support. Satin ribbon bow looks great.
Method of drafting front of the bodice.
Keep A-C on Fold. A-C = Waist length + ½”.
A-O =¼ chest-½”.
From the points A, O, and C draw perpendiculars.
A-B = ½ shoulder width + ¼”
A-N =¹/12th chest +¼” or to taste
A-I =¹/12th chest +½” or to taste
shape neck N-I as shown in the figure
O-D =¼ chest +1½”.O-D =C-E
M-E =⅛” .Join D-M.
B-G =½”. Join N-G
F-J =1”.Shape G-J-D front armhole as shown in the figure.
L is half of C-M.A dart of ⅛” is taken along the line K-L as shown in the figure.
Open the fold of back and front pattern .Now let us do the necessary changes.
Draw a line on the front of the pattern starting from the point N’ on the right shoulder line, going across the front as low as the neck depth and curving to the left armhole.
X is the midpoint of N-B.Draw a perpendicular X-Y to the line N-B it meets the neck curve at Y. Mark that point. Straps are fixed to this point.
Back and front drafts are the same. So cut draft in duplicate. Use one for the front and other as back.
Stitch the right shoulders together. Finish neckline with fitted facing sandwiching interfacing in between. If you want to pass elastic do not use the interfacing. Pass ½” wide elastic whose length is 2” less than the curve of the whole neck line and secure the elastic at the ends.Stitch the sides together. Stitch the darts, Attach the bodice to the skirt portion as usual. Prepare spaghetti straps by using Fabric tubes Fix the spaghetti straps or satin ribbons at the point Y both in front and back of the bodice
I f you want to stitch an “A” line frock take the draft of the front and follow the same method.
