Check that your guitar has strap buttons
Attach one end of the strap to the button at the base of the guitar body
Attach the other end of the strap to the button near the neck or upper bout
If your guitar has only one strap button, secure the other end with a strap tie, lace, or headstock adapter
Make sure the strap is not twisted
Adjust the strap length to a comfortable playing position
Pull gently on the strap to confirm it is secure
