Working like Majura with a dash of Metro.

Every other row is slip stitch (like Metro). And like Metro I think every stitch into the back loop looks basically the same as slip stitch through both loops and working the next DCs into both loops of the DCs (kinda ignoring the slip stitches). BLO might result in a wider shawl because it’ll stretch more, and with wild color variegation a difference might be apparent.

Increased every DC row until 90 DCs wide then stopped increasing. 103 for change row, so should need 102 beads for edging.
