I try to count the squares but I bought the cheap stuff the other day and I'm having trouble finding the perforations. Dang cheap TP.
I've come to the conclusion that five squares= approx one cubit, which is equal to about 18". So, chris, there ya go. Do the math.....
Speaking of mega pallet loads of TP, SOMEBODY promised me a big bunch. I still haven't received that, yet.
