Remember the good old days when there were Liberty shops in a number of cities? I got loads from the Liberty shop that used to be in King Street in Manchester, including fabric for my wedding dress many, many moons ago.
Since discovering Standfast and Barracks (and their ebay shop, katsfsbrics, where there are a number of 3m lengths of lawn for £18), I'm not short of the stuff so I never mind cutting it up.
