The only difficulty I had with trying to do a log cabin was using the wrong fabric...all different weights and wale widths of corduroy (2" wide strips around 8" square centers). Some of it stretched and some of it didn't and my completed squares were not all the same size, so ripped it all apart and used the squares as they were and sewed the strips together to make borders and binding. Turned into my friend's favorite quilt anyway.
Would like to do another one with regular quilting cotton. Had made a pillow with heavy fabric (canvas or duck) that came out really nice. Thought it was a fairly easy pattern.
