Imagine that you need to remember 3 items in order - for example, on your walk, you want to handle some chores:
buy a train ticket
buy wrapping paper
Pause a moment to imagine each of those items: this is a visual memory lesson - so focus on images more than written words!
The BLOKES system is a way for you to use images of parts of your home or other familiar places as a mental storage place for items which you need to recall. If you need to recall 5 exam facts in order then you imagine each fact's image at the first 5 places of your home. Various names exist for this type of system:
Roman Room System
System of Loci
but, in this context, all these labels mean that you think of a familiar place and recall the object which you needed to memorise.
Here is an example system but you can decide for yourself which visual objects to use and in which order they occur; for instance, the order in which your eyes notice the items in your living room might dictate the order in which you list the items here:
The BLOKES system uses 60 familiar places arranged into 6 'rooms' which each contain 10 items:
Note: Their first letters spell the acronym: 'BLOKES'.
Bathroom [B room]:
Living Room [L Room]:
painting / poster
Office [O Room]:
brown wooden cupboard
fire exit sign
line of lever arch files
Kitchen [K Room]:
electric / gas hob
kitchen table / dining work surface
Entrance hall [E Room]:
Hat / Cap hanging up
Phone / Phone entry system
Sleeping quarters [S Room]:
chest of drawers
toy / figurine / jewellery box
For your list of things to do on your walk, associate each chore with one of the places in sequence:
bath: in the bath tub, imagine your doctor's prescription
tiles: on the tiles, imagine the train ticket
shower partition: on the shower partition, imagine the wrapping paper
So, by visiting your well-known imaginary bathroom in its well known sequence of places, you can recall your chores in sequence!
Later, if you have a list of exam prompts to learn, you can imagine each exam image at one of the room places. You will revisit the room places in your well-learned sequence and thus recall your exam images in their correct sequence too.
As an exercise, you could extend the system to 100 items by inventing 4 other groups of 10 places. eg. 1. 10 places in your neighbourhood (even just a small area along a road), 2. 10 shops or 10 parts of local shops, 3. 10 places in your town or city, 4. 10 places in your local park or natural space.
The list of places which you travel through in a sequence does not need to be rooms. It just needs to be something that you can imagine and be able to visualise something beside it.
For instance, here are 50 sketched items which could be used as loci peg locations too:

This way of storing facts in sequence by imagining them at a pre-memorised list of places is known as a peg system or a room system. I would say that a pre-memorised sequence of people is a peg system also.
Why only imagine one item or one story at a 'peg' location? There is clarity that way but it is not a hard rule; if you have the luxury of time, you can imagine more items at a peg location: a story relating to the facts needing recall can be extended; or you can have more items at the location which are not interconnected by a story: the time you spend revising allows you to remember that they are the items that belong at that place.
Some people combine the peg system approach with the story approach; so, at one memorised location, not just one item but several items are memorised because they occur in a single story which takes place at that peg location.
