Double purling?

Does anyone know what it would look like to do a double knitting type pattern but with purls on the outside instead?

It would look like the back side of stockinette. The bumpy side.

Yes, it would look bumpy… I can’t find an example of it, would the pattern come out ok? How does it compare to the knit patterns? I’ll probably just have to do it and see someday when I’m not busy with other projects…

I assume it would look similar to doing fair isle or any other kind of color work like that in purls but I still can’t find an example or comparison…

This video gives you an idea of purling in double knitting. There are several examples at the end.
