My made to measure curtains for a large bay window were from John Lewis and they’re lovely, as was the service. They came round to take measurements and assess the set up, took my order and within four weeks came back to hang them, plus offered to return to steam them if necessary. Gorgeous thick material with blackout lining, floor to ceiling, total cost about £1200. The rest of the windows in the house have ready made and they aren’t nearly as nice!
