File:Wilsons 1819 blanket tartan, border, as stand-alone tartan, centred, zoomed out more.png

English: This is the border (selvedge) sett of a barred-blanket tartan pattern appearing in the Wilsons of Bannockburn Key Pattern Book of 1819. This was originally meant to simply represent the left- and right-side selvedge that would be on an actual blanket, just as vertical lines, without horizontal cross lines. However, the pattern has been woven as a tartan unto itself, and because the Wilsons KPB entry called it "Blanket Sett Border Pattern", it was frequently mistaken for and has been commonly used as a Scottish Borders district tartan. It is often called an arisaid (earasaid) pattern, because the blanket patterns are generally believed to have been adapted from patterns originally used for arisaids, but there is no evidence this particular pattern dates back to the 16th- to early-18th-century wearing of arisaids, or was ever historically used for other than blankets, curtains, and other household cloths. That said, it actually well-enough fits the description of early arisaid tartans as consisting mostly of groups of thin over-checks on a white ground. This sett is only part of the whole blanket pattern; it was paired with different, broader main sett which comprised most of the cloth, and that pattern is available separately in the same category here on Commons, and also shown in combined form.

This version of the image is not exactly full-sett, and cannot tile horizontally or vertically; it is a broad zoom out to give a better view of the pattern as a piece of cloth and to compare well with other tartan images given similar treatement.

Scottish Register of Tartans notes on this design: "Frequently the use of the term 'Border Pattern' has been misinterpreted and assumed to mean that this was a tartan that could be worn by those in the Scottish Borders, but this is not so. The edge of the blanket would have been after the third vertical band of red but the cut-off can't be replicated with this software. Sample in Scottish Tartans Authority's Scarlett Collection." See the main sett of the blanket (elsewhere in Category:Wilsons 1819 blanket tartans) for additional notes.

Produced as a tartan unto itself, this is a normal, mirroring tartan. SRT-provided thread count, in slash notation: /W200 R24 W26 G26 W26 K2 R28 K2 W26 G26 W26 R28 W200/ or in bold notation: W200 R24 W26 G26 W26 K2 R28 K2 W26 G26 W26 R28 W200. Produced as a border, only the vertical part of the pattern would be used (and it would not end with W200, more like W28 to provide a final, balanced white stripe).
