Blue accents and Brown Clamshells

I started to stitch a curve using a blue cotton cord. It was just too thick or my hands were that tired. I resorted to couching it onto the fabric. Next came an echoing curve with a loose braid with the same cord.

That addition just made the three small circles disappear so I removed them.

A large portion of incomplete shell rows moves from left to right echoing the lower corner curve and pulls the sides inward.
