I like the lighter one. but that is just me. if you want it to look more stormy then go darker. maybe a slightly bluer grey more of a stormy color to me but that is kinda what a stormy sky looks to me like a dark blueish gray.

The lighter gray.

I like the lighter one and I think it will be a wonderful combination. Please share when it is finished. I just love those fabrics.

yep, the lighter one.

I like them both. Those are some awesome colors for your geese.

I also like the darker one. It is richer looking to me. The other is very pale and not saturated with color like the geese are. The dark one falls into the back ground and the light one come forward. I covered up half the screen to see which one looked best to me, imho.

The lighter one or black.

I would pick the darker one.

Actually, you might be able to use both - maybe the dark one in the top, lighter one underneath - or dark one going in an arc across the quilt - something to play with and think about.

Both look good. I love the idea of darker for a stormy look.
