Update. Have to correct myself, again, having seen the pattern 'in the flesh' , the 3.5m would make a jacket in any size. I was trying to read the back of the packet on the tablet and it is very small print.
It will depend on the width obviously, but you could make a coat up to size 16 if it is 115cm wide, or any if it is 150cm.
So, a more useful offer than I thought.
