I wanted to do a bit more with it than that underwater scene sanely allows for, so I did a little tryout piece. The white rayon thread didn’t scan well, sorry. I’m not sure what to do with it, probably I’ll incorporate it into a larger sampler with other stitches.
if you start at the top and go clockwise, the quarters show:
lines with alternating “blobs” done in cotton embroidery floss, 6 strands.
trellis made from cable chain, cotton embroidery floss, 3 strands
closely stacked zigzag cable chain, wool yarn
trellis made from zigzag cable chain worked back to back, 4 strand rayon embroidery floss from Anchor
