As I work on the outfit for my mother, I will post progress reports. This is a beautiful hunter green (the pictures make the color wonky) cashmere knit of a light-weight woolen texture. Since this fabric is so gorgeous, I have to style it to the best of my ability. One of the tricks to make professional quality clothing is the nature of the stitches. You can have a bare-bones stitch, or you can bind off the rough edges in a number of ways. French seams, serging, or Hong Kong seams are all valid options. I chose to do Hong Kong seams here.
What you need for Hong Kong seams are 1/2" seam allowance on your fabric, bias tape, and an iron. I made my bias tape out of a funky stash fabric to add a nice contrast (this will not be visible when wearing).
The only images missing are drawing many diagonal lines on three yards of fabric.
Folding the pinned bias tape over the edge of the nice fabric, and re-pinning. The rough edge of the nice fabric is now encased in bias tape.
After removing the pins, and pressing flat -- here is the final edging for the outfit piece. No rough edges in sight!
After binding with bias tape the rough edges of two pieces that get sewn together, I've stitched together one actual seam and pressed it open. This is a finished Hong Kong Seam.
So although this is a laborious process, the finished product is well worth it.
