English: This is a Commons user's self-made approximation of a tartan textile. The design is ultimately from James D. Scarlett (1990) Tartan: The Highland Textile, p. 40 & plate 5(b). Scarlett did not provide the threadcount, just an image of woven cloth; this is a careful approximation of the pattern as shown in the image. Scarlett designed it to illustrate what 16th- to early 18th-century earasaid (arisaid) tartan patterns basically would have looked like, though the design is modernised in mirroring, in having matching warp and weft, and in lacking a decorative selvedge. The real earasaid patterns of the period, which are lost, are believed to have been considerably more complex, with multiple different groups of thin over-checks on white (judging from surviving examples of the thicker-lined but complicated "bar blanket" patterns that earasaid setts evolved into later). [Aside: for some simplified bar-blanket setts, see: [1].] This version of the image is not exactly full-sett, and is not tileable horizontally and vertically. It is a centred and slightly zoomed-out version, for comparison with other tartan images given the same treatment. Threadcount used (this is a typical mirroring tartan, and the thread-count is full-count at the pivots), in slash notation: /LSB4 W2 R12 W72 P6 W16 OG10 W16 R12 W2 P4/ or in bold notation: LSB4 W2 R12 W72 P6 W16 OG10 W16 R12 W2 P4 (where LSB = light sky blue, and OG = olive green).
