Interesting. Is there a USA source? The website says they're trying to get them available in the USA. Or, a source for a different manufacturer that's similar?Something like that just might work.
I can work with 1.5" on each side wrapping onto the back, making a 38" face side out of a 44" roll.What does your process allow?Does anyone have a process allowing 0.5" on each side, making a 40" face side?
I don't get your math. 1.5" on each side, times 2, is 3" so you have 44 minus 3 = 41".
