I could never master the art of Centering! so used to fold g
the paper, leave a dot with pencil, the count the letters of the heading then work it out that way, no one ever knew! and do not get me started of carbon copies, what a mess!!
I remember every friday afternoon taking the typewriter apart and cleaning it thoroughly with that smelly Meths stuff ready for the following week! Not only did you have to know HOW to use it but how to keep it running!. Oh yes and in the bank I did 'shares portfolios' in triplicate and one error and you started again! You soon learnt to respect your machine......
Does anyone remember typing stencils. They had an orange correcting fluid that went all gloopy. You then had to put an ink in the central drum to make copies.
