Thanks for the oak sleepers, they were perfect for my garden project. I've attached some before, during and after photo's. I varnished the oak with 7 coats of epifanes extra UV filter high quality yacht varnish. I've still got to make the coffee table under the parasol. The oak cubes will make great heavy feet.
Many thanks for the photos. The coats of varnish have beautifully brought out the golden colour of the oak railway sleepers and created an amazing pond that is a real centre piece to your garden.
