Half Persian 2 Sheet 4 in 1 AR Comparison
Article © MAIL User: Chainmailbasket_com
This weave has a few unusual properties when compared with other sheets from the Persian family of weaves:
- The weave naturally curls. It will lie flat on a surface with an AR of 5.0 or higher, but even in a large AR, it will curl when picked up and handled.
- When expanding the weave laterally or longitudally, rings are added in the same fashion, row by row, as seen in squarely expanding sheet weaves from the Japanese family, or those containing Japanese weave attributes, (e.g. Japanese 4 in 1, Captive Zen Sheet Full, and Voodoo). The difference is that HP2S4-1 still has directional rows of alternating ring lean.
AR of 6.0
At this AR the weave is fairly open and the interaction of the rings is clearly illustrated. The edge rings in the sample are very floppy.
AR of 5.7
The sheet is pulled in slightly compared to the 6.0.
AR of 5.4
Even more contraction is experienced at this AR. The sheet still has a reasonably relaxed feel to it
AR of 5.1
This is hovering around the area in which the weave can be minimally made (AR-wise) and still lie flat on a surface.
Note: this sample appears darker than the others as its material is from a different wire batch.
AR of 4.8
The weave is forced to curl slightly at 4.8 AR. The right and left sides are elevated slightly.
AR of 4.5
More forced curl is experienced with room for further reduction.
AR of 4.3
A smaller AR gap still contracts the sheet. Things are getting very interesting as any kind of looseness felt in the weave is gone at this point. The sheet at this AR has both the feel and appearance that I would personally consider to be ideal if it weren't for the forced curl. This sample brings about the quesion at what point of expansion would this piece lock up?
AR of 4.1
The weave competely locks up after a few rows at 4.1. Even Half Persian 2 in 1 Spine behaves poorly at this AR.
AR of 4.2
At 4.2, the weave can certainly be expanded further than at 4.1, but eventually becomes too tight to continue. 4.2 will work for Half Persian 2 in 1 Sheet 4 Box/Power Tower as the minimum AR with a small amount of flexibility.

Why does the weave curl?
Each ring in the pattern has a single around the eye (AE) and a single through the eye (TE) connection, laterally, on opposite sides. It also has an additional set of these longitudinally, as it expands the same in either direction. Because of this, two TEs are adjacent to each other, just as the two AEs are. Without any other, underlying connection types, the weave naturally is forced to twist.
