I used DMC threads for the first example. 3 stands on the 2 left rows and 2 strands for the 4 on the right.
The border was stitched with green metallic and I found that very easy to use.
The seam on a CQJP block, has the Cable chain stitched with 2 strands of Cottage Garden thread, called Maple.
I added 2mm silk ribbon and beads
and Tast 2,was Spiked Knotted Cable chain here
