The first one I made I used the 60 degree lines on my ruler. For the second one, I splurged and bought a 60 degree triangle ruler. The new ruler made it sooooo much easier. Even on the tablerunner that was more than the 8 or 9 inches that the pattern calls for. If you have a wider stripe, make sure you allow space to move the ruler down (or up) to the wide part. I love this tablerunner.
