Just that really! In fabric shop today buying thermal lining for dd curtains and seen the most gorgeous fabric reduced to £3 a meter that would go in my living room. I was going to buy curtains but figured I could give this a go. I can borrow a machine and the window isn't huge (aprox 80inches wide with a 90inch or so drop). I thought of maybe buying thermal linings in correct size then sewing the new fabric to them after I've hemmed it etc
