Decide on your colour scheme and pick out your unusual suspects of buttons, pearls etc. Ensure that there is a good variety in terms of shape, type of buttons and shades.

Arrange your mix to form the main part of the necklace.
*If you are forgetful like me, it would help to take a shot of this so you can keep referring back to it.

Once happy, start by threading through your wire to your button. Twist, tighten and repeat.

The back view will look something like this. Keep on going.

Adding pearls are tricky, especially if you want two or more together.
Loop through both ends of your wire through the pearls. Pull and tighten, leaving a slight leeway.
Twist up the leeway you left and push into place.
*Over tightening might cause the pearls to bunch up.

Single pearls are easier!

Once happy with design, twist up the ends and tuck them nicely so you don't get poked.
Pick out your chains next. I chose these slinky ones!
Double them up and wire them to the main button piece.

Wire on a toggle clasp and you are done!
Have fun mixing and matching! The shape doesn't have to be regular so experiment!
