Actually in this case, I think the fairies need to face the same as the other ones. I think the plain stripes are too plain too.
But it doesn't look like you need near as many as you have laid out. Could you go with (From right to left as pictured) lavender, green, white then the dark purple? Maybe stripe so far then add a medallion in the center of the stripe using the green and pink/peach and light blue or something? Maybe even do a white border next - as wide as the fairy corners (that will leave a nice space for nice quilting designs. Then come back with some more styled like the middle. I'm at the same spot on one of mine. I have black, white and bright going on in this one. The large center is done but I have the corners made up already. I've finally decided to just add a wide white strip there where special quilting can be done and add my corners there, then I'll come back with the black, white and brights again before calling it done. Hope that helps.
