It's busy and it's bright, and it's terrific just as it is. I love it!! 8-)

I like it as it is.

No need to calm it down. It is wonderful just as it is.

love it looks really good

I love it - and I agree with the others who have said a black and white sashing would be great - you do have a great eye for color - that is stunning. Try a plain black border with some fussy cut bits from the fabrics you have used - Groovy Man.
(And if you still don't like it, I have orange curtains in my spare room from the 60/70s that it would match . . . .) :roll:

Yes, put a dividing strip, but piece the strip to give you a square in the middle of the bricks on top and bottom and a brick to separate the squares that came together in the middle. This looks fun and funky!

How busy is the rest of the room? Is it "tastefully" decorated in retro, or is it over the top bright, funky and busy? Borders and stripping may work well to give the eye a place to rest if the rest of the decorations are already very busy. Love your colors and design!

How about a big peace symbol appliqued right over the top of it in a solid? It would kind of break it up by being solid (you could do it in black), and a border would do it good, too.

I like it a lot!!! Please put up a pic when done.
