Dale, Laura has had a good look at your neat angles. She is of the opinion that you would make an exellent ' patchworker '. She maintains that your woodwork requires similar skills in working out the angles. I would have though that her material is somewhat lighter than the wood you are using. So , when you get frail and old , think about patchwork ! By the way you mentioned about the 'plastic jug option ' . They have started building new houses here , with the internal walls filled with crushed plastic bottles and other plastic waste. It would be quite reasonable if one lived in this kind of house , to say each morning ' I am surrounded with trash ' It must of been tempting to chop down one of your oak trees. I am sure you eyed them up and down more than once. I have several of these magnificent old boys on our land. I actually burn oak on the fire...............but I leave mine standing. Kevin
