3mm leather straps
 15mm magnetic clasp
 3mm loops

 Jewelry glue

To start, measure your wrist circumference, measuring tape snug against the wrist.

The clasp will add the ease value to the bracelet.

Cut the 5 straps to your size, then thread the loops onto the center strap.

Place glue in the slots of the clasp using a thin stick to thoroughly coat the inner walls. Do not use too much glue; it should not overflow once the straps are threaded.

Keep the straps together in the chosen order and thread them together through 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...
