2πR

While waiting for key man to cut blanks for my new digs, I noticed I was in The Velcro® Section of Astronomy Depot. Spotted multi-colour One Wraps®. Man, they're great.

Then I eyeballed a 2-pak of Velstretch® straps with a little picture of a hog-tied sleeping bag. He's not going anywhere! Oh ho. These might be long enough: 27 inches long!

Did a quick circumference calculation in my head. For my head... Might work. They might work as a stretchy removeable head band.

We shall see...
