I thought I remember someone saying the Missouri Star tute was incorrect in the measurements. I thought it was supposed to be 2.5, 2.5 & 4.5. I can't find the post where I thought this was correct. I watched the tute again and she says 2.5, 2.5 & 4.25. She says it turns out to be 4.25 wide. If my calculations are correct, that wouldn't be right. It should be a 4.5...which way is right?
