First of all, I believe a consumer needs to understand what cabin or tavern grade wood is. It will consist of mineral streaks, knots, worm holes, missing tongues, off-shades, splits, and other blemishes. Always allow 15% for waste when using a Cabin or Tavern grade.
When installing this type of material, work out of 5-6 boxes at a time. You need to inspect each board before installing so you can cut out major defects and use those boards for either starter boards or end boads. Try to use the best looking boards in the middle of the room and in main traffic areas.
Use all other boards closer to the outer walls where they will be covered by couches, chairs, TVs, or other furniture. If possible, put the most defective boards in closets or underneath appliances.
The main thing is to be willing to accept the natural characteristics of the wood. If you take the time to preplan your installation, you should end up with a floor that you will enjoy and admire.
