Each of these sheets is 4 in 1, but some of the rows are arranged differently in the "Biased" version (shown on the right), which alter its expansion. Apart from its angled expansion, the appearance of Biased is different because the Half Persian "peaks" alternating between "squished", and relaxed appearances. On the opposite side of the sheet, the most pronounced lean row pairs come from the "squished" HP3-1 sets, which give a comlpetely different look from standard HP3S4-1, in which they are received one from each HP3-1 chain.
The rings used in this tutorial are 5.0 AR (.308 / .062). 4.7 is a good general starting point for either sheet. 4.5 is the approximate minimum for Biased. These weaves should work nicely above 5.0.
Important note on flipping the weave:
The pieces in this tutorial are expanded to the right. Any time the weave is flipped, it must be done so top to bottom. Do not flip it left to right or you will be putting the row you are supposed to be working on on the left. You can always pick the weave up to add rings, just make sure to set it back down in the same way as shown in the respective step. That is, if you have any difficulty seeing what is going on.
1. Starting with HP3-1, it is important that the chirality (handedness) of your starter chain matches what is displayed here. If not, use the following resources before continuing:

- https://chainmaillers.com/resources/half-persian-3-in-1-left-vs-right.370/
2. Flip the chain over (remember: top to bottom) so it rests on its peak.
3. Start the next row with the first ring. It passes through 1.
4. Add the second ring of this row.
5. Proceed to complete this row by adding 1 ring to each remaining ring in the second row of the HP3-1 chain. There will be 10 rings if your starter chain matched the one in this tutorial. You're obviously welcome to make this sheet as many columns wide as you want
.Note: The rings in this row flop around freely because they lack structure. They can be placed into different arrangements and it's important to use the right one so that the next row added completes the subsequent HP3 correctly. You will notice that the rings connected to cells on the ends of the chains will swivel around, but can always be placed back in the right spot. This tutorial typically shows these rows neatly arranged, however they won't stay that way when the weave is being assembled until they are properly locked in place.
6. This is the same thing with the rings arranged leaning in the opposite direction. This is not the one used in this tutorial. It will produce an undesirable result. There is actually a third arrangement, which will be introduced in steps 18-22 that is used to force the weave to expand on an angle.
7. Flip the weave over (top to bottom), and acknowledge the lean direction of the loose row that is shown here.
8. Add the first ring to the next row (lower right). This first ring only passes through two rings and makes a TE connection, similar to one of European 4 in 1.
The row just started will complete the second HP3-1 chain, which has the opposite chirality of the previous. In case you're wondering why each version of this sheet is being made the same way, it's because HP3S4-1 Biased (right) doesn't start to shift until the third HP3-1 chain is assembled (steps 23-27).
9. Add the second ring to this row. This ring must pass through the same two rings passed through in the previous step, except making an AE connection instead. It also passes though the very next ring. Where the ring added in step 8 went "down through 2", the ring added here goes up through 1, then down through 2.
10. Add the third ring to this row, just like the last: up through 1, down through 2.
11. Add the fourth ring.
12. Continue adding rings in this same manner, always correcting the lean direction of the previous row as you go.
13. Add the final ring of this row. This final ring only passes through two rings using an AE connection (up 1, down 1).
14. Flip the weave over.
15. Add the first ring of the next row. It passes through 1.
16. Complete this row by adding one ring to each ring from the previous row.
17. Flip the weave over.
18. Note: Steps 18 - 22 only apply to the sample on the right. Arrange the rings of the last row in the opposite lean direction.
19. (Only to the right sample) One by one, starting at the top, layer this row by physically placing them accordingly.
20. (Only to the right sample) Manually layer the second.
21. (Only to the right sample) Manually layer the third.
22. (Only to the right sample) Finish positioning the rest of the row. Notice that this row is more "sturdy" than the other two arrangements, which are "natural". The rings can be pulled back out, but at this AR, it maintains its array to an extent. This forced layered arrangement is what causes the sheet expansion offsetting. Please note that the row just added to both pieces, after proper arrangement, still leans in the same direction. Thus the following HP3-1-completing row in steps 23-27 is added the same way to both sheets!
23. The first ring of the next row is added to the top right. It passes through 2, making a TE connection. Notice how much lower this occurs in the Biased version, whereas it lines up with the first row in standard HP3S4-1.
24. Add the second ring, just underneath the first. This ring passes though 3: up through 2, down through 1.
25. Add the third ring of this row. Up through 2, down through 1, just like the last.
26. Add the next 6 rings to this row like in the previous two steps.
27. The final ring of this row goes up through 1, down through 1.
28. Flip the weave over.
29. Add one ring to one of the previous row.
30. Add the remaining rings, one by one to each of the previous row.
31. Flip the weave over.
32. Add the first ring to this row (bottom right) using a TE connection through 2 rings. This is the same as step 8.
33. The second ring of this row goes up through 1, down through 2. This step is similar to step 9.
34. The next 7 rings are added like the last one.
35. The final ring of this row goes up through 1, down through 1, like in step 13.
36. Flip the weave.
37. Add the first ring 1:1.
38. Complete this row.
39. Flip over the weave.
40. It's time to play the row arranging game again. This is a repeat of steps 18 - 22.
41. (Only to the right sample) the proper layering starting from the top is applied, as in step 20.
42. (Only to the right sample) Finish positioning the rings of this row, as you did in steps 21-22.
43. To the top right, the first ring of the row is added, TE, repeating step 23.
44. The first proper HP3-1 ring of this row goes up through 2, down through 1.
45. Steps 25 - 27 are repeated to finish off this row, which finishes the tutorial as well.
