I'd use this role as your practice roll and waste it. Unroll it all the way and examine how it's put together. Then roll it back up and run it through your camera just wasting the shots.

Then unroll it again and examine how you would place it on your spools for development.

This may be a good leaning tool to see how to use this kind of film so that you don't screw up one with pictures you care about.

When I develop it I put it on the spool all the way to the tape then at the end strip off the tape and wind on the remaining few inches.
