Yes, I think they go together, but it will be a very ...what do you call it......not so bland, just a soft colored quilt.

I love the fabrics together. And, you could even add a blue and it will pull out the blue in your flowers.

I am using the Kona Snow/white..and a bright floral for contrast..I find it hard to group so many colors together unless it is a scrap quilt..JMHO..I like all of your fabric but just not together..

The question to ask is "Do I like them?"
(I'm doing the same BOM. Looks like fun!)

We all have different tastes. I like the yellow because it is complimentary to the mauve-ish piece next to it. Also, it doesn't look that yellow on my screen, it is more of a light yellowy lime.

The colors go together. :)

These are all medium values. You need some darks and some lights. Add in a blue or purple to go with that floral print.

The colors go together well,but I would want a darker color in there too--otherwise they are likely to fade into each other in a block.

I can't tell too much from the picture. But, if they look good to you, and you like them, then that is all that matters.

The pinkish color with green dots, the dark grrn dots are the wrong color of green. it may clash with the other lighter green material.
