1. Logs are irregularly shaped and vary in size and diameter.
2. Each log is cut to conform to the one beneath it. (To ensure a good fit, handcrafters preassemble them in their log yard, then dismantle them for shipment to the site.) 3. Sometimes a little bark is left on for color variation and you can typically see marks from the adze and drawknives the craftsmen use. 4. To add character, corner lengths are usually not uniform. 5. Sealant or chinking adheres the logs to each other and seals gaps to make the home weathertight.
