Hi Parsnip,
we have recently made some raised beds from old roofing timbers, they were perfect, very large and heavy, just needed to pull out the nails. We scrounged them from some builders who were knocking down some old cottages near where my parents live, I remember we swopped them for a case of beer that cost £10.00!! Any one knocking down around you? With the warmer weather coming they will need refreshments!!
