I definitely like the second design better (although I also like the look of the first design too).

The blue/green/rust color scheme is very attractive and unique. I can't think of any other tartan I've seen that looks like this. It would look stunning with the blue fields hidden in the pleats to 'flash' when you walk.

I like it better without the second cream stripe, though. Putting that cream stripe in the blue field seems to throw off the nice clean lines. It breaks up the pattern, if that makes sense. Even though you're using a lot of colors and a fairly complex design in the darker portions of the tartan, it still has a nice clean look from a distance. But that thin white stripe in the blue field breaks that cleanness up.

How many colors are you using? I count 7, but I could be wrong. Didn't someone say that most weavers would only do 6 colors?
