I’ve found these three books very helpful. The Sandra Betzina book shows how to adjust the pattern for a large or small bust. I highly recommend both of the Claire B. Shaeffer books shown below. All three books can be found used for less than $2.00 each. Couture Sewing Techniques is the only one that has a Google books preview. I’ve included the photos so you can see the editions I have.
High Fashion Sewing Secrets has “Bias Facing as a Trim”. The single fold bias is sewn to the inside with a 1/4 inch seam and turned to the outside. It finishes at one-half inch. Basic V-Neck in the same book shows how to manipulate the pattern and make changes to the facing to make it fit the V opening better.
I have the soft cover 2001 edition. Couture Sewing Techniques was first published in hardcover in 1993.
I found Power Sewing Step-by-Step at a thrift store. Published in 2000 and 2002. Very nice photo and text presentation. The bias binding techniques are in the vest making section.
