While sewing a log cabin project, and not being too precise, looking at the block when I was finished, I noticed that the logs were not all that straight and were going a bit in a curve instead.
That set me to drawing a new log cabin block where each log is a wedge instead, add some black triangles and there is a new block.
These blocks are paper pieced.
