If the curve is only on the top and bottom margins, but the sides are straight, then anchor the cane at 12 o'clock and 6 o'clock and then set in the rest of the spline in the top and bottom grooves before you anchor the sides. That way the curve is defined. The set the cane into the side panels.
If there is a curve in the top and bottom as well as a curve in the sides, choose which direction has the major curve and partially set the middle of the curve in first, then go to the 2nd curve and gently ease that into the groove. Then back to the first curve and finish up, then the 2nd curve.

You have to understand the physics of the stresses on the cane. If the cane is installed in a single or double curved panel without setting the entire curve first, then there will be more stress on the cane in the center of the curve. If you install the cane without taking into account the curve, you'll see that the cane rises away from the curve in the middle. When you sit or lean back into the cane, you're pushing the cane into the curve and the middle of the panel is being stressed much more than if it fit the curve. It's also uncomfortable because of that extra pressure you're having to apply.
For an extreme example, imagine a barrel back chair. If you apply the cane to the straight sides first, it will be impossible to set the cane into the middle of the deeply curved back - so imagine the stresses on the vertical strands if you could make the cane stretch all the way to the back and how the cane would want to bulge in the back.
So, if you consider these stresses while you're installing a double curved panel, make the needed allowances so that, in both directions, the cane maintains the same stresses everywhere in the panel. That's why, when you're hand caning a double curve, or a single curve, you define the curve first with either step one or step two, then the 2nd step is passed behind the first step, then the first diagonal to lock the grid into place.

    Anyone have any “tricks “ for repairing curved back chairs with pressed cane. How do you obtain the tightness that is “easy” with uncurved/flat surfaces.? I would appreciate any assistance.
