Takseer
Shuffle a name's letters step by step until they return to the order you started with.
Each row takes one letter from the end, then one from the beginning, working inwards. Every row uses the same letters, so every row adds to the same number.
Use a short form of the name. A long phrase produces a matrix of many rows, and the matrix is meant to be written out in full by hand. Choose the spelling you will actually write on the taweez before you begin, since a different spelling gives a different matrix from the first row onward.
