Base (red): a row of ch loops, then rounds of dc/tr posts separated by ch spaces, fanning outward to form the scalloped shell.
Middle (red): dc-fan rounds with ch arches shaping the shell ridges.
Top edge (yellow): a round of dc fans with ch picot loops making the scalloped rim.
Accents (green): sc and dc worked at the base and sides to join/edge the piece.
Follow the color order red -> yellow -> green as marked.
Symbols: oval = ch, X = sc, T with bar = dc/tr, V = 2-in-one (inc).
