"Curtain Panels*. I presume you are thinking of voile or net curtains which just fit the window, i.e. either with tab tops or standard rail fit type. These can be purchased in most shops that sell curtains, but you may have difficulty in getting the exact size you need in ready made curtains. Why not give a few shops a ring, save the footwork, Harry Corrys, Duffys of Earl Street, Hickeys etc. They can usually get them made up for you, and would quote you, but naturally if you have to get them made up for you they will be more expensive than the ready mades - and certainly more expensive that Ikea. Hope this helps.
