Half Persian 3 in 1 sheet 6 is a beautiful dense weave. Unlike the 5 in 1 version, it makes parallelograms (i.e. slanted rectangles) instead of straight rectangles. This can be good or bad, depending on what you're doing (shirts made from this type of weave can be truly stunning!). But in any event, it's a beautiful weave.

This weave works with 5/16" ID 16 gauge rings, although it is quite dense and inflexible; you might be better off with 3/8" ID. 1/8" ID 22 gauge is the only other size I have tried.

You'll need to know how to weave normal HP 3-1 before you can do this weave.

Step 1: Make a chain of HP 3-1, as long as the final sheet should be wide.

Step 2: Place two closed rings on an open ring. Pass the open ring through the two leftmost lower rings on the previous chain.

Step 3: Place one closed ring on an open ring. Pass the open ring up through the two closed rings from the previous step (as in standard HP 3-1 weaving), then up through the leftmost ring on the previous chain, then down through the two rings next to that one. The hardest step in this weave.

Step 4: As in step three. Repeat these steps to lengthen the weave.

Step 5: When you reach the end of the chain, add an open ring with no closed ring on it. This ring goes up through the two rings on its row, up through one ring on the previous row, and down through one ring on the previous row.

That's all there is to it! Have fun with this beautiful weave.
