A woggle is the proper name for a Cub's (or Scout's) neckerchief slide.
This one was made after a moment's inspiration.
Step 1: The idea
Number One Son found a sheep's vertebra last year, and it's been lying around the house ever since - too cool to throw away, too gross to keep.
Then, just as I was putting uniform on for Cubs (I'm a Cub Leader), my eye fell on the vertebra and inspiration struck - it's got a hole in, that would make a cool woggle.
Unfortunately, the hole in the middle (where the ex=sheep's spinal cord used to be) proved to be too small.
