I did this during COVID lockdowns (I never did get locked-down, being medical staff, but I had plenty of boring moments with nothing to do otherwise).

I wound up learning 20, and one of the GPs challenged me to tie them all blind-fold. Which I did, and won a metre of liquorice!

How did you tie the liquorice though?

[MrVandemar]

I was generous and there was quickly not enough to tie even a half-hitch.
