Problem: You want a short, memorable password, but don't find the "horse battery staple" solution appealing (or you do, but can't think of anything other than "horse battery staple" as a key phrase).

Method:
1) Draw a grid containing 6 columns and 6 rows
2) Fill in the letters a - z and numbers 0 - 9 into the grid using the pattern of your choosing (I am rather fond of spirals, but you could try a Hilbert curve, or left-to-right, top- to-bottom, or alternating 3-spaces or whatever)
3) Decide on an "easy" password, say "password" for example
4) Decide on an encoding procedure (1 down, or 3 up, or "knight's move up- right, whatever works for you)
5) Letter by letter, encode your password using the method you decided on in 4)
6) Use this as your password

So basically, you're taking the following information:
1) A password
2) A pattern (for filling in your grid)
3) A pattern (for coding your word*)

And combining them to create a combination of letters and numbers (no tricky characters or upper-case usage here, consider adopting an optional capitalisation scheme as a 4th factor) in combination, the result is a procedure that is easy to remember, but tricky to brute-force.

* An alternative would be to create two 6² squares and use one to map onto the other - but this might take more paper to scribble-on in case you need to recreate the procedure somewhere.

       That’s a bit euro-centric. What about a larger grid with all the mandarin characters on. Then I could choose a pattern to overlay the characters into the grid with (which need not be alphabetical, as the characters are not necessarily often presented in alphabetical order anyway). Then I position my starting password on it, which might be “password”, and end up with ma3 zhuang1ding4 ding4shu1ding1 (or 马 装 订 訂 書 釘 ).

       Yes, that works too, and by extension I suppose, any arrangement of glyphs would equally suffice - as long as you can ultimately type them (or their unicoded- values) into a password entry-box.   

       The downside would be the possibility of having to recreate those codes should you ever find yourself unable to remember the unicode values for 訂書機
