Karen Asks: Wow, thanks Terrell for providing such a comprehensive guide to making Roman shades! I live in Australia, and am interested in adding a swag base(attached picture) to a Roman blind, Do you have any hints, tips or instructions for this particular design?
Terrell Says: It looks like the "swag" is permanent (and very pretty). You should make this as an outside mount shade. Make sure the swag hangs below the window opening when the shade is down.You will have to play around with the online Hardware Calculator to get the correct folding results. The difference between the Lower Drop and the Fold Depth is the part that "hangs down" when the shade is pulled up. This is called the Retracted Border. Looking at the photograph you sent, you will want the Retracted Border to be at least as long as the Fold Depth. That means the Lower Drop should be about twice the Fold Depth. Another way to approach the folding would be to pretend the shade will drop to 1" below the window opening. Use the Hardware Calculator to determine the best folding to acheive the Stackage you want. Now, add the Fold Depth to the Shade Length.
You can follow the online directions for making a Classic shade. The Modified Lower Drop is now the "added Fold Depth" plus the Lower Drop calculated by the Hardware Calculator. Sew on the lift rings per the online instructions. Now you need to make the swag. Sew two tabs in your front fabric and stitch the tops so that they will be hidden by the first fold when raised. Be sure to turn the raw edges under because they will be visible when the shade is lowered. Place each tab the same distance in from the side of the shade as the swag length. Lay your shade on a working surface with the fabric side up. Pull the tabs to the back of the shade and dress the shag. Pin the tabs in place and turn the shade over and whip stitch the back side of the tabs in place.
Also, you should place the weight rod into a fabric sleeve (which matches your lining) and whip stitch it to the lining at just below the bottom row of lift rings. Cut the weight rod about 1/2" shorter than the width of the shade so that the sides don't pull in.
Here is an example: Your window is 33" wide and 60" long. A typical outside mount shade would be 37" wide (2" extension on each side) and 65" long (4" extra at the top and 1" extra at the bottom). I use the Online Hardware Calculator to determine the folding. I specify Finished Shade Width = 37", Finished Shade Length = 65", Ideal Stackage = 10", Battens = Yes, Cord Lock = No. My Fold Depth is 5.5" (11" between lift rings), number of folds is 10, Lower Drop is 7". Adding the Fold Depth to the Lower Drop, my Modified Lower Drop is 12.5". This is were I place my first (bottom) row of lift rings. I must also add the Fold Depth to the Shade Length, so I will make my shade 65" + 5.5" = 70.5" long. You actually cut the front fabric 8" longer than that, per the online directions (and 2" wider).
