One of the common mistakes beginners make when stringing a guitar is to cut the guitar strings short too early. Usually we are tempted to cut the guitar strings once they are taut.
However, do remember that there is a lot of tension in the guitar strings and very often the strings might slip from the tuning peg and bridge. My advice is to only cut the guitar strings when you have fully tuned up your guitar. After it is tuned, you can try strumming a few chords just to make sure that the guitar strings won’t give way.
After you are certain that it is safe, then you can proceed to cut the guitar strings.
