I vote yellow~~

Definitely yellow but how about a brighter yellow.

I ended up going with white. Thanks to everyone for their help. Here is what it looks like. I like it. It is a charity quilt, but I still wanted to like it when it was done. :)

White, with yellow binding

white, it makes it stand out

It is very pretty. Glad you like it now that it is finished.

Yellow is my choice

Very nice. Can't wait to see it quilted. :)

If you have enough of the floral left I would opt for a narrow white border, then add a wider one in the floral. It would give you a touch of all the colours.
Just a thought.
By the way, I love your quilt, adore those fabrics

I vote for white. There is too much yellow in the blocks. The white is the punch that you need
