Good advice to have a table you can walk around. Also, somebody mentioned before that they used a smaller rotary cutter to cut across the top part of the ruler and that is a super idea. I didn't have one so I cut the small part at the top of the ruler with my scissors and that worked find too. Once you do one you will be surprised at how easy it is. DMyers, I love yours with the binding around the outside, that looks SO good!
