This is a different sort of curtain. To start with it fits into the window so that you can layer other curtains over the top.
Before Secret Scuba, I'd never seen these before - and I like the concept very much.
It has 21 Plain and 21 Gingham recolours in MLC Colour Surge palette
There are 1-tile, 2-tile and 3-tile versions which are repositoried, so one recolour colours all sizes. Very nice.
Other CC is Jonesi Blanket Repository Objects from Sims2Artists, using Jonesi Blanket Scuba Recolours.
