The Log Cabin designs this week are good candidates for foundation piecing, though I don’t think you would need a foundation for the solid blocks around the edge of the first one.
The second one has a few set in corners, some involving triangular Log Cabins.
I think all of these are interesting designs even if they are not as simple to put together as square and rectangular Log Cabin blocks.
The one above is my favorite in this weeks collection.
More Log Cabin designs mid week, next week.
