I’m about to pour narrow, shallow, curved concrete footings for brick edging beside a walk – one brick wide, 4″ deep, topping out at grade. What form stock has worked for folks before? I’ve considered benderboard – probably too expensive for the purpose – and tempered masonite. Suggestions appreciated.

Around here, 4x8 sheets of ~1/2" bending plywood is about $40. You could get 96' of 3-7/8" wide material from that.

Get a roll of plastic garden edging. The corrugated Aluminum used to be cheaper, but price for Al products does not seem to have come back down during the current 'depression'
The plasic stuff I've used is 3" wide, 1`/4" thick, and very flexible, have used for curved corners as concrete form with no problems.
What Junkhound said, plastic garden edging works real well. Just have to make sure it's well supported so it doesn't bow out when you do the pour.
However, I have to ask why your using concrete. If the 'foundation' is below grade and not visible, crushed limestone bedding is the common material to use. 4" deep, tamped tight and it should be good for the long run. Concrete, on the other hand, will heave and break with the first winter freeze. That's why they put the lines in sidewalks, to control where the slab cracks when it does.

Thanks. the California North Coast doesn't often get freezy enough for ground to heave, and I was looking to mortar between bricks, to keep weeds out.
I am pouring some curvy sidewalks using masonite ripped to 4" strips, works well and doesn't stick to the concrete. And, it's only $11 a sheet!

Let's not confuse the issue with facts!
Hardi Plank?!??!
I'm confused now. I thought the subject was about flexibility...not durability.

Wet it down well and it becomes very pliable and will allow a curve to be formed quite easily. or use
1/4" masonite, double layer
