I don't remember Tricia's block or a log cabin. I'm going to have to go back and check it out ...
Maybe the places in your area call the Thangles by a different name? But, Thangles is a trademark name. You can order them on line.
How do you think I did that border? It's all half square triangles. And I had numerous points to consider. For someone else's block, I wasn't taking any chances of being inconsistent.
Seeing all the beautiful borders, especially the one with all the blue strips, inspires me to try these things to.
My quilt program is fun to play with, but I seriously couldn't rely on it to help me with the border other than visualizing it. I'm importing all the latest fabric images from all over the websites into my program to work with. It's lots of fun.
Now, where can I find a pic of Tricia's panel? Hmmm. I'm going to start looking through all the pages now.
