You are checking out a lot of vintage pom pom curtains.  They had been hanging in my mothers house since the 80's.  The house was a smokers house.  The yellowing is nicotine staining.  They were used to cover the two different sets of windows in the pictures.  

The set up over the sink had the valance covering at the bottom of the sink and two long curtains hanging. With two tie backs

The set up by the dinner table had the 4 shorter curtains running across halfway up the window.  The valance across the top and The two panels of the longer ones from the top of the window tied back from each of the windows. 

They come with some extra vintage yellowing.  If you are up for the challenge their is a possibility they could be brightened up. Soaking with oxi-clean.  No guarantees you are purchasing as is.  They have been washed once since being taken down. 

These curtains were bought from Country Curtains and were bought some time in the 80's, and similar can be found on the Vermont Country Store Website. These curtains are very well made and have a lot of life in them. 

No wear or tear to the actual fabric.  I think one or two pom poms seem to have a stain on them.
