Get out your rubber bands.
And get two pencils
Get your first rubber band.
Put it on the pencil like so, making a infinity sign.
Add two more rubber bands, NOT making the infinity sign.
Take the bottom rubber band, and pull it over the top. Do the same to the other side.
Add only ONE rubber band this time,
And pull the bottom one over.
So you just repeat the add one, pull the bottom over step until your bracelet is long enough. Once you feel it is long enough, make the shape of the bracelet WITHOUT taking it off the pencil and putti
Putting it on your hand to see if it fits good.
Once you got your bracelet log enough, take it off the pencil and get your c-clasp or s-clasp or whatever.
Attach the ends of both sides of the bracelet to the clasp.
And your finished!
If you prefer it, you can use your fingers instead of pencils.
You can also make a single chain bracelet just like this, except instead if pulling the rubber band over two elastics, you pull it over only one.
