But for these unlined semi-sheer hobbled shades, I wanted something that would not be so visible through the fabric.
Since the shades were so lightweight, I thought I could use ladder tape without rings, and it worked beautifully. The shades raised up without any friction, and the folds readily stacked up on top of each other. The scrunched up ladder is all but invisible through the fabric.
I used my favorite thread- Coats Extra Strong Upholstery thread, which really is super extra strong, and also knots tightly without slipping.
