When you get a splinter, reach for the scotch tape before resorting to tweezers or a needle. Simply put the scotch tape over the splinter, then pull it off. Scotch tape removes most splinters painlessly and easily.

Having said all that some splinters can get very deep and the only real course of action is to use a needle. Before using a needle you should sterilize it. The simplest way to sterilize a needle is to hold lit over an open flame for a second. A match of candle will do.

It can be difficult to hold a sewing needle stable while trying to remove a splinter. To give yourself something easier to hold onto, push the blunt end of the needle into a cork from a bottle of wine until it is very secure. Now you can hold the needle with a sort of handle, making manipulations much easier. Moreover, this needle is a lot easier to store on a shelf in the bathroom, without it getting lost, falling on the carpet.

Using a safety pin can be better as it is also easier to hold.
