Got a pair of el-cheapo polarising clip-ons from My**n for RM7.90. The other stuff used were scissors, box cutter, cardboard, tape and hot-glue gun.
Directions:
1. With the cardboard, roll it into a tube and make sure it fits snuggly on the protruded lens barrel, then tape to secure it.
2. Slit one end all around, then fold it out (like petals on a flower). Shorten the tube (if necessary) by cutting the other end. Make sure that the tube doesn't obstruct the light path of the camera lens.
3. Carefully remove one polarising piece from the clip-on.
4. With a hot glue gun, place a drop of glue at each 'petal', then quickly fix the polarising piece with the concave surface fixed to the 'petals'.
5. Trim the edges with scissors. If you have a craft file, file the edges. Otherwise, a nail file (from the nail clipper) would do.
To use, just slide the polarising filter onto the extended lens barrel, then rotate it until reflections are cut off. If your tube snuggly fits onto the barrel, it will not fall off. The shortfall of using a polarising lens is that you'd probably lose 1 f-stop.

Can make some more... but cannot send. Postage more expensive than material cost!
