Yep me too, got them everywhere, really neat clean and tidy and adjustable for light/shade. I think the made to measure companies are better as getting a really good fit is essential.
I've used www.eclectics.co.uk, very nice but very expensive (£200ish)
Also, www.tuiss.co.uk (natural oatmeal linen and waffle chocolate blackouts £120ish), they were very good too,
but then discovered that actually they are the same company as the much cheaper www.blinds-2go.co.uk. exactly the same fabrics, different names but presumably same quality.
