I like the first one because it is traditional looking and safe. I like the second one because it made me happy when I saw it. Safe or happy, happy or safe - I can't help. Sorry.

I like the original one (circles). It add an unexpected element to the quilt.

The first one get my vote!

I like the first one. Could you use the other for the backing? The colors are so pretty!

We are not going to make this any easier - I like B, but personally tend to veer away from traditional

1 is gorgeous and like every one else has said very traditional. 2 is more fun. Depends on what you want. I love 2's fabric. Not much help, huh?

You quilt is a knock-out.

The reason I prefer the first one, A, is because the piecing in the star is intricate and really wonderful; I feel the "bubble" background takes attention away from this. That bubble fabric is adorable for another context, maybe even on the back of your quilt where it won't compete so much with that star design.
Can't wait to see what your finished project!

I like the 2nd one

I like B. I think the tan frames the star and would show off the quilting. I think the circles would make a great back.

Think A is the best.
