Either would look great. Your quilt your way.

Well... I voted yellow border the first time, but I really do like the change up in the inner border to yellow if you want a gray outer border. The double gray border doesn't emphasize the yellow as much, (which really is fine if it's the look you like though!)

I do hope to see the final result either way, it's a super cute print!

OK, I heard long ago to use the darkest color in your quilt as your border as it acts as a frame to keep the eye in on the quilt. But what I would do if no deciding I would use the yellow on the top and left side and the gray on the right side and bottom borders, then you would have the best of both, LOL but then I hear my own drummer.

Love the Bunnies by the Bay fabrics you have chosen. I have made two quilts using it and have plans for one more. I used a solid soft yellow for the final border with the yellow print for binding. But of your choices, I would use the yellow. Happy bunny quilting. And post a photo of your finish!

Children are always attracted to brighter colors...it helps to stimulate their minds.

Like all the alternatives but love the yellow inner border with the wide grey border. You can’t go wrong no matter what you decide.

The yellow really brings the quilt together.

I like the yellow best.

For a single border I prefer the yellow. But I like the double border better, then would bind again with the yellow. A dark grey binding would be my second choice, matching fabric would be third.

Happens my next project to quilt down/last project finished, has a narrow yellow inner border, a blue/green outer border and then will use the yellow again for the binding. It's quite a bit brighter than your top but I wanted the contrast, plus I bought a bag of fabric at the goodwill that all the fabric came from, and that was what I had the most left. I put a picture of it in this thread:

I agree, I think the narrow gray is too dark. A lighter gray or the yellow would be a good choice. If using yellow I'd go with the gray border, otherwise I love the yellow with a lighter gray.
