Cut your strings to the appropriate size. I generally cut the top string to be a little over a meter long, and both of the sidewall strings to be a little less than a meter.

Melt the ends of the string to prevent fraying. After melting, I lick my fingers and pinch the tips of the string to create a pointy tip that is easier to string. Have caution when pinching the tip, if your fingers are not salivated, you will burn yourself.
