Person 0 to 9 

If you had to memorise digits of a long number then the BLOKES system might not work well. One reason for this is that you would be imagining a digit at each location  but digits are not as memorable as pictures involving people. What if each digit has an alternative appearance: the appearance of a person. So 0 to 9 would have 10 people to represent each of them. Here is an example  just using drawings of people. However, you could choose anybody famous, I suppose, and use them as your 0 to 9 people.
0: Oliver:
1: Alice
2: Buck
3: Nick
4: Doreen
5: Fay
6: Seb
7: Guss
8: Henry
9: Weex
So you have a sequence of places in which to imagine your information; and you convert hardtoremember ideas into images which you have low difficulty picturing in your head.
In this way, with training, 1000s of facts can be stored quite accurately in your memory.
I use spellings in 2 ways: to represent digits from 0 to 9:
