Let’s be clear. There IS a difference between projection and return.

Ever get confused when the workroom or installer asks you what the hardware return is? Or what projection do you want on that valance?

Projection and return are two different things. The best way to explain it is this way. Projection is going from the wall out. Return is going back to the wall.

Drapery hardware projection and return are shown in the diagram above.  As you can see, the projection is the whole bracket measurement from the back of the bracket to the front. The return is measured from the middle of the rod back to the wall.

 

Fabric returns back to the wall. For drapery panels the return is the fabric on the panel side that folds back to the wall and blocks the light on the sides.

Boards and hardware project out from the wall. For board mounted window treatments, the projection is depth of the board.  The return is the fabric that is on the sides of the board mounted window treatments.

Shutters and binds project out from the window.

 

 

Knowing the difference comes in to play when ordering hardware or specifying a valance that has to clear shutters or blinds.Here’s an example of what can happen if you don’t understand these terms.

A designer specified drapery hardware for a window with existing shutters. At the measuring appointment the workroom was told by the designer what the bracket return should be. Panels were fabricated with the  return measurement that was given.  But when ordering the drapery hardware, the designer thought that the bracket projection and return measurements were interchangeable. At the install, she was shocked to see that the bracket return was much too small for the panels to hang clear of the shutters. The panels would not clear the shutters and thus laid over the top of them.

Calculating Yardage for Traversing Panels

One part of our job as window treatment professionals is to calculate the correct yardage for traversing drapery panels. These calculations involve several steps.

First exact measurements of the window must be taken correctly and in all of the right places. Be sure to use a measuring sheet so that you will not forget any important information.

Secondly, the finished width, finished length and fullness are determined. This information will need to be discussed with the homeowner and/or designer to make sure the drapery will cover the area desired. (We will be using the measurement for the whole window width plus the amount of wall to be covered on each side.)

Thirdly, we need to know what fabric and linings will be used.  Does the fabric have a repeat?

After this information is gathered, we are ready make our calculations.

  1. Multiply the finished width by the fullness amount and add 27”. Then divide this number by 54” to find out how many widths of fabric are needed.
  2. Add the hem and header measurements to the finished length to get the cut length.
  3. Divide the cut length by the fabric vertical repeat to find out how many repeats it will take to make up one cut length.
  4. Multiply the vertical repeat by the number of repeats to arrive at the total cut length. This will be longer than the cut length. Round up this number.
  5. Multiply the number of widths needed by the total cut length. Divide by 36” for the number of yards needed for the whole window.

Once the face fabric yardage has been calculated you must also calculate the lining yardage using the same method.
