Danish cord is a little tricky, the chairs that utilize this material and weaving tend to want to collapse under the pressure applied when weaving a new seat.  If this should happen when I start your Danish chair seat replacement, I still require payment in full.  It is a much more involved weaving process, very time consuming, physically demanding, and the material is pricey. 

The material is something like the fiber-rush, but even stronger.  It is smoother in appearance, and works up beautifully...these pictures do not do justice to it's beauty.
