Hi,
I'm new to rotary cutting. I have the June Tailor Shape Cut Slotted Ruler and the Olfa Rotary Cutter & mat. I'm a little confused do I line up the bold 0 line on the ruler with the 0 line on the mat? Or do I line up the 0 on the ruler with the bottom fold of the fabric? Does it really matter at what number the what the fabric is placed? Thanks, April :)
