Pretty simple really. Takes a table saw or jig saw, some sandpaper, a heat gun, a few scraps of wood, and a few C clamps or vice grips.

Photo album for the email folks is:http://www.gmcmhphotos.com/photos/how-to-make-curved-pvc-valences/p46624-r-0012.html

But the text is here:

This is what I started with, a 36" piece of 4x4x1/8 vinyl from Lowes.

Then I marked the profile on a piece of 2x4. In retrospect I should have made the cut more in the middle...more on that later.

Just verifying the fit.

Cut the 4x4 into four 1 1/2 x1" angles on the table saw. You could use different sizes as necessary but this is what I used for my Micro Mini Blinds. If someone will tell me what kind of depth is needed for the day night shades, I'd appreciate it.

Clamp in place. It will twist and warp. Not to worry.

I used a Harbor Freight heat gun on high and as the PVC get hot it flattens out and stretches. Make sure it is down all over the curve and let it cool before you pull it off the form. Remember what I said about making the cut in the center of the board? If I had, I would have had a male and a female pattern and just pulled the two together as the PVC was heated. I'd do that on the next batch.

I cut a slot in a piece of plywood, cut a 1" strip of PVC, heated it, and once it bent, set a weight on it while it cooled.
