I have a customer that called today, and he wants something done around the playground set. He would like to have rubber mulch, but he is unsure about the edging around it. I suggested railroad ties, and he didn't like that at all. Next I told him about the 6 x 6 x 8 timbers. Then he told me that he doesn't care too much for the square look. Any Suggestions?? Also if you could share any jobs that you have done.
