The Tracy valance is made up of several pieces which are sewn individually installed in layers. One way is to use our clip rings. If the fabrics are too thick for the clips to bite all the layers we then use our tack gun to attach the gussets to the valance then we use the clip to hold only the main valance piece. Another option if you are not using our hardware, is to use a draper pin to slip through the back of the main valance piece after you have used the tack gun to connect the gusset, then hook it onto your hardware. Call us if you need further clarification.
