Flat-back blackout reverse mount hobbled shades

Flat-back blackout reverse mount hobbled shades.  That's a mouthful, right?

It's important to remember, when talking about "blackout" lining, that it is the LINING that is blackout, and not the TREATMENT.  The lining is blackout, but the treatment is ROOM-DIMMING.  The only real blackout treatment would be plywood nailed over the window.  Just about any window treatment will have points of light bleed.
Even this three-layer blackout treatment from a few years ago- blackout drapery, shade, and cornice- allowed some light bleed.

For that reason, room-darkening is a big issue in the shade fabrication world.  There are two sticking points with shades: one is the "pinholes of light" that are the consequence of stitching- the needle pierces the black inner layer of the lining and the tiny holes let light through.  The other issue is the "light bleed" from the sides of shades, whether inside or outside mounted.

For this project with Denise Wenacur, we wanted to make outside mounted room-darkening hobbled shades.  Hobbled shades eliminate the pinholes of light problem because the row stitching is hidden by the "hobbles".  The light bleed at the sides, however, is enhanced because the hobbles stand out from the vertical plane of the back of the shade, like this hobbled shade we made last summer:

We decided to make flat-back hobbled shades.  The flat back and the reverse mount allows the shade to hug the wall as closely as possible, minimizing the light gap.

When raised, the flat back folds up with the hobbles:

I hadn't made a flat-back functioning shade in a very long time, so I was feeling my way for this project.
I fused a coordinating lining to "Silky" blackout lining (from Angels Distributing) but in retrospect, next time I'd order a color-coordinated blackout lining and use it alone.  I marked the horizontal rows before taking it off the table to prepare the face.

For the face fabric, I made a mockup out of the cutoffs from the sides.  I was able to work with the pattern repeat so the hobbles are pleated to pattern.

Two different finished lengths required twice the planning!

I pinned the bottom so I wouldn't forget how the layers were sandwiched.

The two layers were first joined at the bottom, at the weight bar pocket.

Then the shade was laid on the table and the face fabric pinned to the flat back along the rows lightly marked with a pencil.

 I worked my way across, double-checking the lines on the flat back which I had marked earlier.

From the back:

And there, friends, is where the photos end!  Sewing these rows is JUST A LITTLE AWKWARD, which helps explain why I have no photos of that step.  After that, it was inevitable that I would forget to continue to document!  But the rest of the job was pretty basic.  

Rings were sewn to the back, and the shades strung (using Ring Locks) and rigged just as if it were a flat roman.  These were reverse mount, which means that the fabric comes off the back of the mounting surface- in this case, Rowley's EZ-Rig headrails with velcro, positioned as far back on the mount board as possible.  

Grommets in the shade allow the cords to come to the front and attach to the lift mechanism, and a blackout-lined topper blocks the grommet holes.

Pleating to pattern worked out beautifully- in this photo, see especially the bottom right which shows the pattern well:

There was another 128" wide x 27" long window for which we made a short hobbled shade that folded entirely up under the valance when raised.

This job was quite an adventure, and we were thrilled at how well it turned out!

Extra long shades

Our workroom has standard 8' drop ceilings.  I had an order for 4 shades 42" wide and 99" long.  Since the shades were being shipped to Florida, I was not going to be at the installation, so I had to find a way to hang them.  Enter John: he took out a 48" ceiling panel, extended our hydraulic stand, and we raised them up into the ceiling so I could level them!

 

Not only were these shades long; they also were blackout lined with my no-pinholes method and ribs; and because circumstances necessitated mounting them on the molding, they also needed to be reverse mounted with a valance.  I used my standard no-pinholes method with ribs, which means working from the inside of the shade.  The combination of Bella Notte Duette (bonded with flannel) and Bella Notte Silky blackout makes a very handsome and substantial shade.

My favorite lift system for a reverse mount is a system such as Rowley's EZ-Rig, whose headrail comes with velcro on one side.  The shade goes on the back of the headrail so it will be snug up against the window molding and let less light in the sides.

I hand-basted the layers together at the top, then fused Dofix velcro to the face.  I did worry because of the weight so I took the totally completed shade to the machine and sewed the velcro for extra security.  This was a little awkward because the ribs and weight bar were sewn inside the shade, but since they were only 42" wide I managed it.

I left the basting stitches in and I left the raw edges- blackout linings don't fray, and the fused velcro hid the face fabric raw edges.

Each lift line needed a grommet for the cord to pass through to the front.  They need to go as high up as possible without causing any buckling; I usually put them about 6" below the top.

 

The shades were strung using Ring Locks from SafeTShade in order to be compliant with the safety standards.

I wasn't sure how long the valance would need to be to cover the grommets.  After the headrails were mounted on the boards we raised one up with a piece of paper taped to it to see how long to make the valances.  

The self-lined valances had to go 1" farther back than the board, so they would reach the wall.  I wanted to fit them with velcro to make the underneath more accessible for the installer, so I mitered the corners of the valances and added Dofix fusible velcro.

That is sweet!

Regular hook velcro from Rowley was stapled to the back edge of the board.

 

They fit beautifully and the installer's job was easier since he could peel back the corners to hang the shade.

 

Eventually I hope I'll receive photos of the installed shades, but for now, a table shot will have to do.
