Full Persian is a weave that imitates the look and feel of rope. This tutorial is for Full Persian 6-1; Full Persian 8-1 is possible with larger AR's.
Full Persian takes an AR of ~5.5 and up. 22awg 1/8", 20awg 3/16", 18swg 1/4" and 16swg 5/16" make a chain with a nice amount of flex. (Note - depending on the manufacturer of the rings, 16swg 5/16" might be too tight. If you don't already know if that ring size will work with your preferred ring supplier, go with 16swg 3/8".)
Metric sizes - approximately 0.6mm wire/3mm ID; 0.8mm wire/4.8mm ID; 1.2mm wire/6.4mm ID; and 1.6mm wire/8mm ID.
New rings are gold and old rings are silver.
Step 1a: Spread the rightmost 2 rings apart, and slide the leftmost 2 rings forward and between the spread rings. Spread the right end of the middle pair of rings open. It's tricky to hold them like this, so move right on to...
Step 2: Pass the 2 pre-opened rings between the middle rings from the previous step. The new rings should go through the eye formed by the right- and leftmost rings from the previous step. Make sure the new rings don't end up connected to the middle rings.
Step 3: Put 2 rings through the rings you just added, one on either side of the vertical rings.
Note: You can repeat steps 2 and 3 to finish the chain. Once you get a hang of it, you can move on to the speedweaving technique. The speedweaving technique may not work with tight AR's, in which case just use Steps 2 & 3.
Step 4: Close 2 rings and put them on an open ring. Pass the (horizontal) open ring between the spread (horizontal) rings, and through the eye formed by the 2 pairs of (vertical) rings. Arrange the new vertical rings so there's one on either side of the old vertical rings.
Step 5: Pass an open ring through the eye and the 2 closed rings from the previous step.
Now just repeat Steps 4 & 5 (or 2 & 3) until you finish the chain.
