On adventures away from home I like to send postcards.
In New York I was surprised to find the museums and galleries had rather poor postcard selections.
I bought 'From head to Hand' by David Levi Strauss and in it found that the Inca's thought writing memories down helped them go away, where as tying knots kept the memories alive, passing information on to future generations.
I thought by tying knots I might be able to describe my adventure in more detail when I got home. Fortunately I was carrying red and yellow Jaimson's DK (£2.80/25g)
I only tied 5 knots before it was tie to catch the plane, but it does work -
The knots represent more than the places visited, but I won't write about that for risk of forgetting.
