Just to add a further note - if you are using the technique in this book - the Marti Mitchell ruler has a blunt tip and she advises leaving the tips on throughout the process to enable you to match up the points. This really helps with assembly. So if you get one of these rulers, with hindsight, I'd try and find one with it's tip. Otherwise just rotary cut past the tip to get the point. You have to take the 1/4" into account when deciding on strip width but it's all clearly explained in the book. Dunster - we should contact Maxine and ask for commission! LOL
