I read in one of the other threads on tube quilting that one of the tutorials is wrong. It says to cut the fabric at 4.25 inches and it should be 4.5 inches. Since I haven't made any of these (YET!) I'm not sure which tutorial it is that is off. I wanted to point it out though so others can be aware of this. From what I understand, if you cut it at 4.25 inches, all the points get chopped off.
