Home-made remedy to para sa mga hindi nakakabili ng magandang foam tape. I'm not saying it's better than the famous ones, but if you're on a low budget, maganda to.
All you need is an old ping pong racket, old is better because you're going to have to destroy the racket.
There are 2 sides, one red, one black. Pick whichever and rip off the rubber part. Make sure not to damage the foamy layer beneath it. This is what you will be using for the "tape"
Put the racket over a lighter/fire for a few seconds then pull it in and out of the fire, after 5-6 times, slowly peel of the orange/yellow/whatever color layer.
Cut a small rectangular shape slightly bigger than the board and place double sided tape on the back. Attach it to the board and trim the edges to your preference.
The tape takes a little while for it to be really worn-in. Place duct tape on top of the tape and rub a coin on top of it for as long as you want until you're happy.
The end-product is not that good, and is like poop to the more famous brands, but it is better than plain sandpaper. You might also need to wear it in regularly because it kind of loses it's grippyness from time to time.
