If that is the look you want, then you can have a runner made up for you.

That's good to know. But I don't necessarily want it made... I mean is that even a thing? Anyone have pictures of that?

I'm just curious what others find,is a good solution in this scenario. Perhaps no runner at all?

Just about any major carpet store can help you by making a custom runner and not too pricey. The cheapie way would be to get 3 short rugs (all the same)

HD offers a limited variety of runners thru a vendor and perhaps vendor can do custom runner

If not custom, get a longer runner and have it cut and bound at the end. Many flooring stores have the necessary binding machine -- just ask.

Thanks everyone!

So it looks like getting it cut and bound would be best and something not unheard of. I think that will be best solution. We can select runner we like out of a standard length and then have them adjust that corner.
