The original seam is on sharonB’s blog. This seam and the previous seam were counted as 1 seam and detailed under the 2nd day.
This is a simple seam – A ricrac is tied down with detached chain stitches.
Ricrac was tacked down with a single strand of pink thread. Three detached chain stitches are worked on the peaks on both sides. I have to learn to hold the ricrac and work the stitches.
