How
a Top-Down/Bottom-Up Shade
Folds
When you design your Top-Down/Bottom-Up Shade you need to visualize how
it will look in all positions. Do you want the Valance to be long enough
so that you can completely hide the shade when it is raised? You can do
this by making the Valance at least 1" longer that the Stackage
plus the Headrail Length. How low do you want the shade to drop? Many
people plan on only lowering the shade part-way down since they are
hiding something or will always want privacy.

TOP-DOWN STACKAGE - Usually at least
8". You may want to never fully
lower the shade.

Make Top-Down Only Roman Shade
I have
already told you that the Top-Down Stackage is the same as the Bottom-Up
Stackage. This is true if you look at the fabric shade by itself.
However, you also have the Headrail, which adds to the
"apparent" Bottom-Up Stackage.

APPARENT BOTTOM-UP STACKAGE - Usually between 10" and
24" (for very large windows).
I like 12" to 14".
Examine the drawings above to understand the Rules of
Folding:
Rule 1. Top-Down Stackage equals the Top Border plus the Lower Drop. This
is the MINIMUM Top-Down Stackage (that looks nice, you can drop the shade to the
floor if you want, but it will look strange). You can have a larger Top-Down
Stackage by tying off the cords. You may want this because of privacy issues
with the window you are covering.
Rule 2. APPARENT Bottom-Up Stackage equals the Headrail Length plus the Top Border plus the Lower Drop.
Rule 3. THIS IS THE IMPORTANT ONE! The APPARENT Bottom-Up Stackage is equal to the
Top-Down Stackage plus the length of the headrail length. This means that the Bottom-Up
Stackage (what you see when the shade is pulled all the way up), is always
larger than the Top-Down Stackage (what you see when the shade is dropped all
the way down).
Rule 4. Fold Depth = half the spacing between rings
Rule 5. Fold Depth MUST be less than the Lower Drop (or the front
fabric will be exposed to the sun when raised).
Rule 6. Unlike a regular flat Roman Shade (only pulls up), the Top Border can
be as small as you want it to be as long as there is room for the Stiffener
Board Pocket.
