A pressed open seam is one that has two seam allowances that are each pressed flat it's own side of the seam.
- Remove any loose threads or remaining pieces of thread before you begin mending.
- Pin the seam being sure to keep the original seam as lined up as possible. (Pins are not shown in the photo for clarity purposes)
- To start the needle is anchored as close to the seam as possible, in one layer of seam allowance, two to three stitches from the un-sewn or ripped area of seam. On lightweight fabric it is best to anchor the knot on the open part of the seam allowance.
- The back stitch is then started where there is sewn seam to reinforce the end of the sewing and start the "mending".
