I figure a yard of fabric - after washing - has about 35 x 40 square inches of usable fabric , which is 1400 square inches

35 x 42 = 1470

It looks like odd shapes that wouldn't cut very efficiently - and if you are using the paper piecing method - and want to fussy cut for design -

??

Omak I take my hat of to you and Bearigrey, you just have stunned me with how you work out the fabrics you need.

Having looked at the design again and again, I think some of the fabrics will have to follow the grain so that will account for some wastage.

Think we are all agreed I need fat quarters though.

:D

Love ya all for helping me

I LOVE math! The actual size of the quilt is 68 x 78 which equals 5304 square inches.

5304 divided by 144 equals 36 square feet, with a remainder of 120, maybe 7/8 ths of a yard?

so, then I took the square inches in a fat quarter = 396 sq inches x 20 (if the ten light/ten dark figures are fat quarters) x 20 = 7920 square inches which works out to - - hmmm... 55 square feet ...

that looks like it would be enough to make the quilt and then some! But, we know that is where scraps come from, so more is good, right?

I have to know if my math is correct! The square foot thing eluded me in my first post ... thanks bearis gray for filling that part in!
