Kitchener stich with ribbing

I’m trying to join to pieces of work with the kitchener stich.
It’s ribbed 3/1.
How am I supposed to do the purled stich?
Thanks

I remember answering a question a lot like this. Hmmm… oh well, I must be going crazy. What else is new? :roflhard:

Anywho… you treat the purl stich just like you treat a knit stich. Just keep on grafting like the grafting fool you are ^_~

Sorry, I really AM going crazy…
