I wonder why you could not add something pretty to the cordwood set up. My neighbor is building a cord wood art studio that is about 16 by 20 and I do believe (besides having a zillion large windows ) that he is doing some of the old glass soda bottles as well just for the nice colors! Cordwood is an enormous amount of work (by the way, spraying the body sap with PAM then waiting a couple of minutes makes it come off really easy, even off of glasses if you were wearing them!) but sure makes some lovely homes. I am concerned about the current cost of cement you face though, will take a bite out of the old wallet for sure. Have a wonderful time, keep us posted and don't forget to strut with pride at your accomplishments once in a while too!
