Our very own Dunster designed and wrote a pattern for Diamond Log Cabin. She uses it as her Avatar. You might want to try PMing Dunster to see if she still has copies of the pattern for sale. She self published it and the quilts that have been made from it are drop dead gorgeous.

Here is a link to one of her posts about it. http://www.quiltingboard.com/picture...ed-t55682.html

I think I made one like this about 20 years ago. If i remember correctly it was from a magazine called Quilt. They had a feature of easy patterns by Sunbonnet Sue or something like this. You start with a 2 1/2 inch 90 degree diamond and work it around just like a regular log cabin-however many colors you want. I probably don't have the instructions anymore but maybe from this someone can help you figure it out.

If it starts with a triangle, it might be a "Twisted Log Cabin." Here's a link to one I found on Google... http://myquiltplace.com/photo/windmi...sted-log-cabin

Are you thinking of Barn Raising Log Cabin. Just google that. I can't read the rest of the thread as eye drops aren't working this a.m.

There is one in an ebook available from Annie's e-patterns called "Inspirations from Precuts" on page 37.

I think Eleanor Burns has a diamond log cabin pattern.

A book with several diamond/triangle patterns called "Not Your Grandmother's Log Cabin" by Marci Baker may have a design that you are looking for.
