Luxury interior furnishings firm Walker Greenbank is doing so well it's "comfortably" beating pre-recession levels, driven by growth at its wallpaper and fabric printing factories.Profit before tax for the six months ended 31 July leapt to £2.31m from £0.57m in 2009 on revenue up 16% to £33.67m.Half-year sales of printed fabric and wallpaper were up 27% and mid-market brands of Harlequin and Sanderson performed strongly, with Sanderson revenue up 17%."We are now selling more product than ever before, comfortably exceeding pre-recession levels," said chairman Terry Stannard."The momentum in our first half sales has continued, and we have traded well in the first ten weeks of the second half. We enter the autumn selling period with confidence of delivering a strong full year performance."The interim dividend of 0.15p a share is the first interim payout for 13 years.
