Finished Measurements:
Width 59 inches (150cm) and length 23.5 inches (60cm) measured form top to bottom at deepest point (after blocking)

Gauge:
16 stitches and 36 rows to 4 inches (10cm) in stockinette stitch, after blocking
Gauge is not crucial for this project, but changes might result in a smaler/larger shawl and therefore a different Yardage requirement.
