I agree with Dunster. Whatever you decide will be great. Really pretty blocks and it is YOUR quilt.

Definitely the green. Beautiful!

4 patch posy with a different fabric from the same line would look awesome too. So many options!

The blocks look great! Have you considered black? If these are the 2 colours you have I would go with the green. Remember , " Colour gets all the credit, but contract does all the work!"

Your blocks are fantastic! I like the quasi matches.....because the blocks are, themselves busy and I don't think you see that the corners don't match. But in time that may bother you. So, a good alternative, I think, is the green. It will, I think (can't tell without a full view) set the blocks off and showcase them. As others have said, I'd also consider sashing the blocks.

This is going to be beautiful!

I like the green best.

Of the 3 choices you have asked about I like the dark green the best. If you do the setting triangles in say the dark green, then do sashing w/ corner stones, keeping the corner stones the same color as the setting triangles and the sashing a contrasting color it will look like you have alternated the octos w/ a churn dash (or monkey wrench) type block. I have seen it done w/ other octos and it looks great.

The green just makes the blocks pop, very pretty.

I love the green, I actually gasped out loud when I saw that picture. I think the print corners are way too busy, the eye needs a place to rest. And I think the cream is rather blah.

I like the green too.
