Just take a pen and paper and do your calculations as you play with it.
One jelly roll is normally 40 strips ... so those 40 strips @ 40 inches give you 1600 ....as in Jelly Roll Race 1600 x 2" (finished seam).
Of course, it's a little less, because of all those seams, but whose counting?
Then when the first seam is sewn you have 800 x 4"
2nd .... 400 x 8"
and so on .........
So if you used 50 @ 40, that'd be 2000
1st .... 1000 x 4"
2nd ..... 500 x 8"
3rd .... 250 x 16
125 x 8
62-1/2 x 32
31-1/4 x 64
As you can see the the sizing kind of goes wonky on this one.
However, if you try other numbers .... 55, 60, etc. you may find it works more to your liking
And of course, who says you have to stick with 2" (finished) strips?
You could cut other widths.
So pen and pencil ... and your favourite cuppa and calculate away!
(and yes, some of the other numbers do work in better proportions than the 50 I did for you)
