Sorry for the awful picture but here is my sample for the Week 11 Build a Seam challenge. I took the Buttonhole Pyramid stitch and then mirrored it underneath, leaving a space of about a quarter of an inch between the rows. Each peak of the pyramids was topped with a french knot and three detached chain stitches. Then in the center between the peaks went silver spacer beads attached with a seed bead. On either side of the spacers are more detached chain stitches.
The quality of the picture is awful but hopefully if you click on the picture to enlarge it you can see the details.
