Mr. K. Brown,
Thank you for you kind remarks. Your comment on lanolin caught my eye.
When a sheep skin is processed or tanned the lanolin is extracted, by many different means because it is a highly sought after lubricant for a great variety of uses. The processed sheep skin has very little to no lanolin left in it. It maybe that some processors try to leave some in or put some back in after the extraction and tanning process but I have not read of that.
Perhaps your experience using sheep skin in humid climates has caused it to stick to wood and metal but I rather doubt it is a cause of the lanolin which is an oily preservative and lubricant, and used in some instances for water repellants.
If you have more information on this I would be interested in knowing. Thank you.
