Repeat as many questions as you have to, even if it is the same question, the simple answer is yes it is easier to work with all the way around, there is no easy way to accurately cut the width of the fabric, and you don't want to be trying to repeatedly stack a big piece either, you can use more than one repeat at a time, though I don't recommend more than 3 at once,
It also depends on what book you are using to what they are telling you to do,
