I found out that 630 yards, like the pattern states, is not going to be enough. I am already into my 3rd skein (660 yards) and have one more chart repeat to complete. So its probably going to be around 750 yards needed instead.
I ended up using almost all of the 4 skeins of patons classic wool worsted (840 yards), there is not much left maybe 50 yards.

I just finished my second wrap and it took less yards than the first wrap, but still more than the pattern states. I used almost all of 3 skeins of Shepherd’s wool, which is 750 yards total.
