I am planning a shelving project for a flat in Scotland. Her at home in the
USA our 3/4 inch thick boards come in 2, 4, 6, 8 and 10" widths, minus 1/2
inch for planed boards. I didn't think to look at B&Q last trip over to see
what widthsare common there. Can anyone tell me the common width closest to
8" sold in the United Kingdom?

Thanks in advance.
