Made some slight mods to allow me to join as I go:
Round 4 - ch 3, 1 dc into arch from hdc, ch 1, 2 dc in next space, ch 1, (3 dc, ch 2, 3 dc) into next space}, ch 1, 2 dc into next space; repeat 4 times, then repeat once to }, ch 1, sl st into top of chain.
Omit Round 5
Used the ch-1 to join to ch-1 spaces.

Did one round of sc in the Rococo (tan) as edging around the whole blanket to give it a finished look.
I also could not keep the pets off this blanket, hahaha!
