bingo - more than 1500m

78 sts too wide on 4.5mm
64 sts good width but not drapey enough on 4.5mm
Try 56 sts on 5mm? Even less sts on 5.5mm??

3 jan 21 - oh glorious blocking. Lost faith last night and almost frogged it bc the fabric was just too dense. devastating. But have it a wash and block out and it’s happily drying and almost twice the length! I think it will be just fine. Hooray!!
