Look at this beautiful antique log cabin waiting for adoption at the antique mall in my hometown. I didn't have a ruler with me, but I think the logs are 1/4". It's a top, so the block backing is visible - foundation pieced. Some of the fabrics are shredding, but what a beauty! The brights look like silks. There is an embroidered name on one of the logs (picture at left). You never know what you'll find.
