Abstract: Present invention provides a cost-effective way to implement window curtain(s) movement control on a vertically-oriented and generally round track, where a bendable “I” track will be placed along the shape of a round or curved window frame, with a plurality of rollers moving along the a bendable track, either “I” track or “C” track, where some magnetic buttons on the mounting pieces may provide for the pre-set locations for the curtains to easily set and adjust to these locations when the curtains are moved about in a fan-like fashion around a pivot center.
