Hello Beth
I've measured 140/2 as 62 wraps/cm and 70/2 as 46 wraps/cm
So the formula is multiply by 62/46 (= approx 1.35)
That's the formula for a photocopier which enlarges both the length and
the width.
Many scanners/computer software enlarge by the total area. If that's
the case then you enlarge by
1.35 x 1.35 = approx 1.8
Hope that makes sense.

about breaking threads. I can use my scanner to copy and resize the
pricking, but need to know how much larger to make it.
