Al N Al’s version of the Tartan.
This was 8 harness twill, on a 12 dent reed. Problem was I only had a 17” reed so the pattern was only one way, Count inches rather than threads, The Scottish registry publishes the thread count as
W12B56K48G48K8Y12 meaning white 12, Blue 56, Black 48, Green 48, Black, 8, 12 Yellow.
