Is there a local quilt shop you can take the quilt to? Then you can match either the blue you want, or one of the other colors in person. It'd be cheaper to pay the $11-14 for the 1 yard than to pay shipping again from an online place and have it be wrong. Yes, trying to match online is difficult unless you know the exact full name or the number off the end of the bolt.

Are there any sites that you could send in a scrap of your fabric and see if they have a match for it?

Although I would be reluctant to part with any of it - - - -

Then I would use the middle light color since it has similar colors to both the dark and light lattice, and bind w/ that far left darkest.

It almost looks like some of the VIP/Cranston mottled prints that I have.

How much do you need?

I seriously doubt you will find that same blue, because of dye lots. If it were me I would use the middle one. I think once stitched on and quilted it will blend well with the lattice strips. It will be a very pretty quilt when finished.

Is your 1/4 yd enough to do a 1/2" strip (cut 1") around the edge, or binding? If so I would do that and add a border of the lighter fabric as it picks up the lighter blue in the floral fabric

That is what I was about to suggest. I think the ones on the right are too bright.

That is a very cute quilt! I think that if it were me trying to decide, I would order the one I think is correct and then decide it IS correct and finish it on up. The other fabrics can always go in another quilt. This quilt is just too cute to not finish the way you want it. (I say to decide the fabric is correct because you know it probably won't be perfect....)

do you have more piecing to do or just a border you need fabric for? if border, use either of the blues to the right. I think you've tried hard enough to match exactly. it will turn out well so go for it.
