You're almost embarrassed because you're crafty, frugal, and likes to think outside of the box? Job well done!I'm almost embarrassed to admit how I did it. I cut the leg off an old pair of really big sweat pants and squared it up. I used hem tape to make a nice hem at the bottom. I put pieces of hem tape on either end to form side seams, and then lined up my watches and put down a piece of hem tape between each. The hard part was then removing the backing to the hem tape. Then all you have to do is fold up and press down so that the tape sticks. (You can get the tape at any craft/hobby store.)
I can tell you what degree a camshaft needs to be on an engine with variable valve timing on both intake and exhaust valves, but you got me on this "hem" tape.
