Crux by Henrike Bratz. This was a new tangle to me so I tried a couple of different versions first before getting into my "tile". This tangle has lots of variation possibilities, some because I just put the line in the wrong place!
For my tile, I decided to use a pencil grid. I really like how it turned out. Now I'm wondering, did I even need that grid at all? Might have to go play some more!
