HII don't know if this will fit in with the context of your songs......... but in years gone by there used to be "bleaching greens" around the cottages. These were large areas of grass where the flax (used to make linen) was left to dry, (and bleach), in the sun after, (or possibly before!) they'd done whatever it is you do to flax.
There are good examples of this in "The Ulster Folk Museum", just outside Belfast. (Sorry, just thought I'd stick in a plug for home.)
Hope this helps.
