My dad used waxed string for so many things. I'm sure his reel started off looking like this one
But when I inherited it there was only about a third of the reel left.
A long length of it went into my holiday emergency kit and has been used and reused on many adventures. It has been a makeshift washing line, I've used it to measure spaces, to tie up things, to secure things....the list goes on.
At home I've mended shoes with it, wrapped parcels for posting and I've secured sets of books for charity collections with it. Every time I've thanked my dad and it has always been called "dad's string".
The most recent job it did was restringing my beaded light pull cord in the downstairs loo, R & E made it for me when they were three years old and last week when rushing in there while saucepans were bubbling on the cooker it suffered one tug too many and beads scattered all over the floor. Now restored.....
Which sadly after the last 18 years just leaves me with this bit, which I know I'll be reluctant to use.
I can't replace it, I'll just have to manage without it.
