Always learning

 I just learned how to tie my shoelace a better way -

The knotting method I learned as a child was not the best way!

For months I have tying double knots on my laces to stop them coming undone - But I have tested Ian's knot and it works well - not coming loose. As an ex-scout I should have known reef knots are better than granny knots.
