Imagining images at peg locations is a good way to memorise prompts of text which you want to memorise. You can also use pegs to store tabular information or a sketch.
The following table assumes that 6 peg locations are needed per table cell of information. Eg. Sulphuric Acid, if stored at a cell of the table, might use 6 pegs as follows:
Note: A cell is one of the rectangles of a table - just the place where a fact is written in.
1. The image for SU; 2. the image for LP; 3 the image for HU; 4. the image for RI; 5. the image fro AC; and 6. the image for ID: spelling Sulphuri..Acid.
I had to trim it a bit to make it fit in the 6 pegs!
(Maybe SU and AC would be sufficient for you to remember that you are meant to write 'Sulphuric Acid' at a cell.)
It would be far better to already know an image to represent sulphuric acid (something I mentioned in the calendar article).
If a 4 column table can have its 4 headings prompted by 4 images then the following table needs those 4 pegs plus 560 pegs. That's a lot but it might be worth the effort in an exam 'fact cramming' situation.
| Heading 1 | Heading 2 | Heading 3 | Heading 4 |
| Pegs 1 to 6 | Pegs 7 to 12 | Pegs 13 to 18 | Pegs 19 to 24 |
| Pegs 25 to 30 | Pegs 31 to 36 | Pegs 37 to 42 | Pegs 43 to 48 |
| Pegs 49 to 54 | Pegs 55 to 60 | Pegs 61 to 66 | Pegs 67 to 72 |

If a cell only needs 3 pegs to prompt spell a word then the other 3 pegs of the cell are dormant. That is a bit wasteful but it helps to be disciplined to not complicate the recall of the table.
Another use of a peg system is to draw a sketch such as a biology diagram. I wrote a separate article about that called 'Grid Sketching'.
The basic idea is that, as you travel from peg location to peg location, you find an instruction to plot a point on a grid or draw a line from that point to another point; and then there are other ideas like 'how would your peg system tell you that an annotation should occur on the graph?'.
The grid probably will not be seen on the drawing you would make: the grid is typically intended to guide you in where to plot and draw on a page.
