Instructions for the D20 bracelet and variant.
First Step
String the dice on the thin core cord and tie a temporary knot at one end.
Second Step
Fit the 550 (thicker) cords through the buckle, pull through approx. 3″ of “size insurance” cord and tie each with a temporary knot. 
Third Step
Loop the 550 cords around and through the other side of the buckle. and measure around your wrist. leave a (finger width) half inch of additional room because the braiding consumes diameter.
Fourth Step
Unlock the buckle, CAREFULLY SO YOU WON’T LOSE YOUR LOOP MEASUREMENT, and insert the unknotted thin cord through the buckle. (2 inches will be enough)
* You will now have two 550 cores, one thin core with your D20, and the two 550 cord “arms”.
Fifth Step
Braid all three cores to the buckle with cobra pattern loops. 
Continue cobra pattern until you want to add an item to the bracelet.
Decoration Step
Each time you want to place a decoration on the bracelet follow these instructions.
Start by lifting the thin core up from the bracelet. 
Now braid a single cobra past where it if lifted.
Slide the item down the thin core and loop the 225 cord back with the 550 cores.
Now lock the decoration into place with a minimum of two cobra braids. the spacing is up to your preference.
DO NOT TIGHTEN DOWN THE 225 CORD AND DECORATION BEFORE THAT STEP. YOU RISK PULLING APART YOUR COBRA.
Finishing steps.
Untie the temporary knots holding the buckle, and on the 225-core cord.
Fit all three through the buckle so the extra cord is aimed to the wrist side/ inside.
Put the bracelet on and resize it now.
Carefully take it off, fold the tail ends against the original cores and continue using the cobra pattern to lock all the tail ends into the core of the bracelet. Tightly secure your last braids.
Cutting step.
Leaving approx. 1/4 inch (1 cm) of cord trim off any extra cords.
Fire step.
Notify your instructor when you are ready to have the cut cord ends melted.
congratulations!
Variant Steps.
This series of steps will introduce the half hitch / zipper braid to create a variant on the full cobra D20 bracelet.
Begin by repeating the previous steps until you have approx. 4 cobra braids finished.
Half hitch switch!
Keep in mind that half hitch used in this variant is not structural and easily slides on the cores.
Choose one “arm” and loop over the cores, the lead end will travel up through its own loop staying on the same side it started.
Alternate with the opposite 550 cord forming the half hitch zipper look.
continue the pattern until you reach the point you want to add the dice.
Decoration Step
Each time you want to place a decoration on the bracelet follow these instructions.
Start by lifting the thin core up from the bracelet. 
Loop 1-2 half hitches to support the dice, then lower the dice and continue with the zipper pattern until you approach the buckle end.
Finishing Steps
You must switch back to cobra braiding to lock the buckle inn place following all instructions from the previous finishing step.
Repeat cutting and fire steps.
congratulations!
