As I have been doing a number of posts about Plaid and Tartans (one and the same in the U.K.) on both blogs, I feel I need to do a disclaimer and explanation of my use of the Registered Tartans. (I've shown the Texas Bluebonnet first on January 3 on Possibilities, etc. and again recently, and the Alpine Meadows, as well as the Millenium Ribbon.)
I have contacted the Scottish Registry, and am told that it is definitely a copyright infringement, and therefore illegal, to make charts of these to sell.
It is O.K., however, to use them as I have on these blog posts to demonstrate how to interpret and set up a tartan/plaid for one's own use. The same method applies to other plaids one sees and wants to convert to needlepoint. I used the Tartans simply because I have loved them for many years.
The Bluebonnet plaid has gorgeous colors - and is also the state flower of my home state, Texas. Green is my favorite color - hence the Alpine Meadows, shown in the picture for progress!
I have shown my little canvas doodles where I worked out the counts, and you are welcome to use those for your own enjoyment - but NOT to make charts and sell. I also have planned tutorials on how to USE these plaids to create actual projects - I've managed to lay out a checkbook cover with this green one, as the pattern elements fit. (These will probably be on Possibilities, etc.)
My daughter says she would like the Burberry tartan for hers. Of course she would. Later. I offered to make also a dog collar for my SIL's big yellow lab, Godzilla, but it was declined, as was a belt for SIL - however, many many people are making plaid belts!! I'll show this process also.
Anyway, the gist of this is that one may replicate a registered tartan for PERSONAL use, but not for commercial. That is to say, not for financial gain by selling charts and patterns.
I do have a book on creating and using Plaid, which also includes quite a number of plaids I've created myself - but these are totally original, and not registered tartans. The book is being revised (in my spare time) and updated, and will be offered as an e-book soon, I hope, on my web page.
