How to keep consistent tension with intarsia knitting

Looking for some recommendations for how to keep consistent tension with intarsia knitting. If I knit with the same tension throughout, the intarsia sections are tight at the ends, and if I loosen up, the whole section looks sloppy. Any suggestions would be helpful (not a newbie, but haven’t done this for a really long time)
thanks in advance. :XX:


I’ve done quite a bit of intarsia, but have never had a tension problem. All I can say is that when I switch colors, I just hold the old color over to the left and bring the new color up from under it. When I purl across the back, I think I give it a little pull to snug it up, but that’s it.
