I bought one at Peekaboo Dubai a year ago. Loved it. Used it so much for breastfeeding, and also to cover pram while baby was sleeping. It is fantastic to be able to bf in public places. They have gorgeous prints as well. They delivered at my door step in Arabian Ranches - no charges. Delivery was delayed one day - got bib and burp cloth with apologies. Very sweet! Very pleased with the cover I got. Got just one and do not think I needed another one. It dries so quickly.
There are others called Hooter Hiders - very similar but also about the same price. Is there a reason you need more than one, Orchard? I bought 2 but honestly only have used the one. Otherwise I second the tailor idea - here's a pattern you could even take along.
