I found this name brand ladies belt at a thrift store for less than $2.00. It has some tarnish on some of the metal parts, but that's okay. I buy belts mostly for the buckles to make other jewelry but couldn't pass this one up for the price. You will need a cool button (I changed my mind on the button as you can see in the finished piece), something strong to cut the leather, some type of cording for the loop, and not shown...an awl or some other way to make a hole in the leather for the cord and button to go through. I used my dremel, worked great!
You see these nice, expensive fabric scissors? PLEASE do not use nice dressmaker scissors/shears to cut leather. Thank you! But you do need something to measure your wrist and an optional marker.
Measure wrist and cut the belt piece that measurement or a little larger for comfort if you don't want it snug. Look at the belt and be sure to cut it at a nice, undamaged spot. Punch or drill a hole on each side of bracelet and attach button to one side with heavy thread or cording and run a piece of cording through the other side for a button loop. I used 3 strands of satin rattail cording and braided it for the button loop. Be sure and knot cording on the inside of bracelet really good and tight. You could add a dab of glue to make sure your knots don't unravel.
