Festoon Blinds

These are curtains with extra pulleys to gather the length, but as this can cause problems it's worth looking at these as a separate topic.
This diagram illustrates how the cords, used to draw the bottom of the festoons up, are threaded through a number of hoops (or they may go through any kind of channel that keeps them in line). These go right to the top of the curtain where they all turn towards one edge and are passed through all the remaining top hoops. By pulling each of the cords in turn, when the curtain is in place, you can make sure the gathering is level, or shaped to your taste, and once happy with the length they can be tied off so they don't move. The gathering should be let down for cleaning.................
 .....so the cords must be undone and the curtain stretched out. However, letting the cords out of the hoops is a mistake and leads to lots of string all in a tangle at the end of the wash. Instead, push one safety pin through each cord and pin it onto the top band just above the top hoop. Take another safety pin and put that through the end of the cord attaching it to another part of the curtain. This ensures that you know where the end of each cord is when the wash is finished and you simply have to rethread the top hoops to gather the bottoms again.

Finishing (Ironing)

Festoons are very similar to plain curtains once the cords have been let down. Here we have a representation of ironing a festoon curtain. As with plain curtains there is likely to be some gathering left even after undoing the cords at the top. There's no need to iron the tops themselves as there's a band at the top and ironing it could cause damage to the face of the curtain. Instead move the curtain head off the board and be prepared to iron up to but not over it. Then, working from the lead edge and pulling the curtain towards you iron the top section, making sure any lining is flat before you start or you may cause a shine. Be certain not to go over the hoops or any banding that the hoops run on.....
.....otherwise it may cause shining. Move on a section at a time making sure you do the next section that hasn't been done. Remember as the top is gathered there's more material width below the top than actually at the top. This means your going to have to maneuver the curtain to ensure you don't miss any of the fabric. Continue moving section by section until you've completed the whole top part then, if the curtain is longer than the ironing board, shift to the bottom section starting once again with the leading edge, pulling the curtain towards you. Now you don't have to worry about stretching as the fabric will naturally lay flat, but you still need to be aware of any linings that may crinkle underneath or any hoops or bands that the hoops are on.
