3mm leather straps
 15mm magnetic clasp
 3mm loops

 jewelry glue

To start, measure your wrist size, taking the measurement snug against the wrist.

The clasp will add the comfort value of the bracelet.

Cut the 5 straps to your measurement and then thread the loops onto the center strap.

Place glue in the slots of the clasp using a fine stick to coat the inner walls well. Don't put too much glue; it shouldn't overflow once the straps are threaded.

Keep the straps together in the chosen order and thread them into the clasp. If a strap gets stuck, don't force it! Flatten the end with your fingers and try again. 

And there you go! Beautiful creations ...
