Thread: Stop stripes, flaps -- troubleshooting help please

Hello,
For a while now I've noted that I damaged the lower right corner of my Walkin' Horse strop. (IOW, the corner on the right, closest to the rings that I hold.) I have trimmed off the flaps or glued them down, when able. I have lightly sanded it, but have never really gotten that area to be smooth.

I have also noticed the parallel stripes you can also see on this image, and they are fairly close to the other damaged area.

I pay pretty close attention, I thought, to keeping a light touch on the razor, keeping the spine against the leather, keeping the strop taut, etc.

Any advice would be appreciated.
thanks
