I'd do a new pattern with at least some red in it.

thanks--that's where I'm leaning. Anyone else?

I don't know, I'd maybe do solid red accent pillows (that match the red in the wingback chair pattern) OR you could do another patter with red, but I'd do a completely different pattern, nothing too similar or it might look too busy or like you're trying to match but don't.

What other colors are in the room? Pillows are a great place to bring it all together.

I like the idea of another pattern with the right colors. The only thing I don't care for is when people mix it up with multiple plain colors and another pattern. Like they couldn't decide what to do so they do everything.

Perhaps a stripe that has the red and the yellow, as well as other colors from the red print in it. But I would make the red and the yellow the less predominant colors in the stripe or check, and have a third color be the star.

get some green with red prints to go with yellow. All are happy colors and will look great together.
