Command Hook Ukulele Strap Button

I've had this on for about a year

I bought these walmart for under 5$

make sure the opening of the hook is facing the right direction

I made one out of an old tshirt using the many finger knitting tutorials on instructables.i tied one end around the headstock and the other around the hook.

I haven't removed it cause there hasn't been a need to.and the ukulele it's on is fairly inexpensive,so I'm not worried about damage.
it's worked great so far.
