I have a doorway arch that I need to drywall. The width is 34.5 and drop is 10" I calculated that to be about a 20" radius. Is this too small to use 1/4 drywall? I have tried wetting/scoring the front and back, doesn't work. I am now setting the strips in between 2 sawhorses and wetting them every hour or so to get a natural bend in it. I also have the cutout of the arch, so I turned it upside down and used it as a form and placed another wet strip over that. Is there something I'm missing? Is the radius too tight? Any suggestions?

As Bud said just use the flex corner bead.You will be putting a substantial layer of mud that will cover the whole arch so it does not have to be perfect.Just score the back paper on the 1/4" and go for it.Bud was speaking of bendable plywood but I can't think of a brand name off hand either.
I prefer to use Easysand powdered mud with a 45 minute set time on arches.Mix only what you need as it sets from a chemical reaction.Do not get the Durabond in the brown bag.
