I don't think so. I often put two kinds of fabric together for shirts ~ interlock & rib knit, jersey & interlock, etc. I think the hemp and the C/L rib that I have are pretty close weight wise. Of course the hemp isn't as stretchy as the C/L rib. I do have black C/L though, so that's another option ~ to not use the hemp at all. But isn't that what you wanted, lol??
