Mocking up a skinny shade with spring lift system

We hastily mocked up a skinny shade to test the smallest (1.2) Easy Spring Plus cut down for a 16" shade. There's no room in the tube for a stop on such a narrow shade, but since the spring is so small it doesn't have much "oomph" so it just naturally stops on its own. John adjusted the rotations so it stops right where we want it, without an actual stop. We mocked this up because we had a half dozen skinny shades to make and wanted to test the parameters first. FYI, I lined this sheer with a grey voile, just for fun. The shade has only two lift lines, and a self-fabric pull tab is sewn into the permanent fold in the back. I spent way more time than I should have, trying to level this stubborn little guy. Shades with two lift lines take a lot of fussing because you can't average the cord tension over a series of lift lines. I also discovered that the wavy pattern created a disparity in the fabric "give" and I didn't quite hit the center of the wave so it has a permanently wonky look. And...... that's why we make mock-ups!

Our new dig: front pull tab for spring roller romans

We are diggin' this front pull tab, hidden under the permanent bottom fold.

This is an outgrowth of the back pull tab, which I've been using all year instead of a pull ring.

Spring roller shades do not strictly require, but work much better with, a permanent fold at the bottom, to make it easier to engage the spring mechanism and not over-pull the shade.
We used that permanent fold to hide a pull tab, made of self-fabric with a bit of flat bar inside so there'd be something rigid to grab hold of.

We made the shade our usual way, adding 6" for the permanent bottom fold.  This shade is interlined and has ribs sewn in.

We turn the hem into a machine-sewn weight bar pocket which provides security and stability, and that is where the pull tab is sewn in.  Here, the shade bottom is folded back so you can see where we pinned the tab.

The bottom row of rings are held by tiny twill tape tabs for even more security.

The raw edges of the tab are trimmed after it's attached.

The hem is folded back to encase the tab.

The second stitch line is sewn to complete the weight bar pocket.

The weight bar is slipped into the pocket, and I also added a rib to keep the bottom hem perfectly straight since this fabric is a little loosey-goosey.

When the shade is strung, the bottom two rings will be pulled up close to each other with an orb and then tied.

Ta-da!
