I thought the orange would work, because it really brings out the orange in the quilt center. It brought the small star background immediately to my eye, when they had been "absorbed" by the movement in the quilt background with no border at all.
Then I thought the blue would work because it actually tamed the movement in the border by focusing on the blue in the quilt. It gave the blue a reason for being in the quilt center.
Honestly, when I pulled the fabric from my stash I did not think it would be this blazingly bright. It iw a bit unsettling for me, who deals mostly in darker, more subdued fabrics. My usual brights are those of the primary color wheel!
These are off the chart!
So which one do you like best?
Frank, who actually has some eye for placement and color, really likes the orange.
