I'm going spare trying to find any curtains with a vaguely child-friendly design which will fit the drop of the window of our 18 month old's room - we'd need 250cm or more, but the standard sizes seem to be up to 187cm drop. We've only found very "grown up" designs in the longer length we need. Any recommendations? - not least since I'm next to useless at making anything myself as well as trying to avoid getting them specially-made (and expensively-made)...Many thanks!
