Our experience with the installation of the tracks was very straight forward. The tracks fit perfectly, slide with ease and are barely noticeable. Luckily we had the painters trestles to help as it was a 5.7 meter drop. My mother (a seamstress) sowed our curtains with a vertical join so they are not at all visible. We are so happy with the results and the curtains get most of the attention/compliments in our new home. The beautiful S fold curtains make our house feel homely, sophisticated and stylish. Thank you for helping us to achieve our desired look.
