Before the thread turns into a "Why isn't this woven in PV" thread, I think I should clarify something for people to see things through the eyes of a retailer.
Unfortunately, we have to weigh the 'commercial viability' of ANY tartan we'd do in a special weave (minimum of 130 M or roughly 40 to 50 kilts). The tartan must be of substancial 'desirability' (by our estimation). If we can't sell through the material in a year, it's money that would probably be better spent elsewhere on other inventory that we turn over more quickly.
The only way around this for tartans that would be slightly less commercially viable is to have a group of people (35 to 45) order Semi Trads and or Casuals in a particular tartan in one shot. This gets us at least CLOSE to the material yardage used in a special run (130 M).
While I PERSONALLY like Brown Watch (it's on my list for future kilts) it's not our most requested tartan.
The Colorado State tartan isn't one that we've considered, though we WILL be having a special run of 1 state tartan in PV in the near future... check back in a month or so.
