Welcome to SRP and the str8 razor shaving community!

Try laying your strop on a counter top until you develop proper technique, it will also save ruining the edge. Practice with a butter knife with the strop hanging to develop proper technique and establish muscle memory plus it will help prevent cutting your strop. As mentioned before take your time, there is no rush. Str8 razor shaving has a large learning curve, it doesn't come over night.

Happy Shaving!
