I have a really awkward bay window but from the instructions given on the blinds2go website it was really easy to measure up for roman blinds. I had free samples sent to choose my fabric. Once ordered I was given an estimated date of dispatch and my blinds actually arrived a few days before this date! My one complaint if I had to find one was that I didn't receive any message to say my blinds had been dispatched. Fabulous blinds, great service and great quality blinds. Would definitely use again and would definitely recommend.
