Hi Neil
I guess it depends on how much you need.
but you could buy… lets say 5 metres of fluorescent at 610 wide and ask the supplier to slit the roll up into 50mm wide rolls. makes it easier to handle too…
so you will get
x12no. rolls
50mm wide x 5m long
I sometimes do it with my rolls of digital vinyl and also banner material.
i.e. Banner roll 60 inch wide – so I get it cut into x2no. rolls 30inch wide. as it helps with waste doing it this way for smaller banners.
hope that makes sense. 🙂
