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:
