Got started on this over the weekend, cutting tons of pieces!! I have all the blue and all the color in the border cut out.

Wow that center already looks spectacular!
In your earlier posts I thought the first version looked wonderful and very balanced even though you thought there was a lot of blank space. However size can make a difference in the actual piece, so it may show different in real life than the picture.
All the colors hanging look really good together too. I'm sure it will be fantastic. Good luck with it.
