Creative Grids Stripology Ruler - Question about length of cutting channel
So I have a June Tailor 18" Shape Cut Plus. I've enjoyed it but have nicked several channels so am looking to replace it.
I've seen lots of complaints saying that the cutting channels on the Stripology are too short to fully cut a double folded piece of yardage. I saw the ruler today and see that the one inch entry point narrows at 1 inch and the one inch exit point widens at 13 inches. That's 12 inches of blade-accessible cutting space times 4 equals 44 inches. Most fabric is 42 inches wide, maybe 43. Am I missing something?
TIA.
