Purple for me

I would probably use a strip made up of all 3 colors alternating in no particular pattern, with maybe bits of the print thrown in.

I kind of like the contrast of the orange.

RED!!

I agree the mauve brings out the good color in your fabric

What about using both the orange and purple? 2.5" strips. they really complement one another and would pop.

dito!

I like the redish/orange.

Not the blue..

I think the orange one -it brings out the flower pots -the little shed roofs and it seems to play better with the off-white back ground
