Squares
24 x 28 = 672

Weights

Round 1 x 21 middles - 11g (0.52g each)
Round 2 x 21 squares - 29g (difference - 18g / 0.86 each)

Whole Blanket - 2110g
Yardage between 5,500 and 6,000 (estimated)

Estimates:
Border approx 8 rounds of 40g, so 320g?
Therefore rest of blanket about 1790g?

R1 took 0.52g each, so 672 of them would be: 350g
R2 took 0.86g each, so 672 of those would be: 578g
Therefore 672 squares would be: 927g
So joining (R3) would be: 863g

Duck Egg colour: 863g + 5 x 40g = 1063g (11 balls?)
I’m sure I broke into the 12th ball though!

Roughly 92g (270 yards) of each colour?
(Really it’s a bit more of Patons Smoothie and King Cole Smooth as they are heavier, bit less of Belissima/Bambino as they are lighter!)

Belissima:92g x 4 = 368g (1078 yards) per colour
Bambino: 92g x 3 = 276g (808 yards) per colour
-plus border yarn: 1063g (3115 yards)
Total Bambino: 1339g (3923 yards)
This makes total yardage at about: 5540 yards

Whole blanket weighs 2110g
Approx 237g of that is Smoothie/KC Smooth (530 yards)
Therefore approx 1873g is Bambino/Belissima (5458 yards)
This makes total yardage at around: 5988 yards!
