Do you need curtain tracks?

I've gotta replace the old curtains with some new ones. MIL has no time to shop for them. I've gotta do it for her. She likes all those floral -patterned ones, which to me, looks drabby. I prefer to have in a more contemporary design like stripes. Those will definitely brighten up the living room far better than floral ones. And oh, she reminded me to get new curtain tracks too whilst at it.
