Skinny border added-thank you Maggiemay!
 

Glad I didn't attempt to miter these borders-I have a 4" strip of the dark blue border fabric left! Whew! I added cornerstones of the outer border to accomplish the effect I wanted. Thank you for the suggestion, Maggiemay! I think next time I will just do the borders separately....but this project needs to be done asap, so I took the path of least resistance! It's raining and the lighting is terrible-the blues are rich and the medium blue is so pretty. The lightest fabric is also blue-looks white on my screen! Close up is more accurate....
Thanks everyone for your input-this is the best group of quilters ever! :)

Very striking! I really like that block and the colors of blue you picked.

your quilt is stunning, awesome blue!

It's a beautiful quilt! You are welcome- Glad we could all help you figuring out!

This is beautiful. I, too, love the colors!

Beautiful. The block is cool--and I love those colors--especially the cobalt blue. To have a 4" strip left, though? You must've been sweatin' it!

Stunning. great colors.

Very pretty!! I love those colors!

Beautiful quilt!
