After an hour at the sewing machine, the first round of topstitching on my Batjacket is done. I learned about stitching a needle's width away from the seam and doing another row of stitching 1/4" parallel to that. I have to say the longer stitch length and double stitching really gives the garment a professional look. In fact, I spent five minutes pulling out a row of topstitching that I accidentally did with the wrong stitch length because I wanted it to look professional.
The techniques I'm learning with interfacing, sewing without pins, and topstitching have been fantastic. My Kings jacket will be even cooler.
