You pick a little at one end then gently holding the top seam in your left hand until the stitching is just under tension, you snick away at the stitches with the rotary cutter in your right hand. Be careful not to stretch the seam out of true. I only do this for PP and then I use my small rotary cutter so it's more manageable - I think it's around an inch across. :-D
