I am moving, and I want to package my strop in a box so that it doesn't get damaged. I remember when I got the strop, it was curled loosely (12" diameter circle) but I don't remember which side was facing out. What's the ideal way to package it? It's a Tony Miller practice strop so it's not stiff, but it's not overly bendable because of the thickness.

Thanks!
