    No pressing open the seam?

    It would have been helpful to have mentioned that the second stitching line was a zig-zag and the stitch length and width adjustments that would be necessary depending on the fabric. All that is not so visible in the video. Also, the second stitching line can be straight stitched as well with good results, depending on the fabric.

    Dear ustabahippie, Thank you so much for watching and commenting. In the print version of this technique, you wil see we do also address using straight stitches to sew the seam allowances together. As this was just a demonstration on a knit fabric, we used a zigzag stitch for visibility. Stitch length and width adjustments for various fabrics are important, you're absolutely correct, but it wasn't within the scope of this segment to address all of the possibilities. Again, thanks for viewing and remarking!

    Hi user-1141318, since the seam allowances are going to be sewn together, it's quite permissible to just press the seam as sewn. Thanks for commenting!
