Could you please tell where you got your cat pattern at

Love this cute quilt! It would be a little work but if you could increase the 'boxes' with the same flow of design, keeping each one still separate, that would fun. You could use one of the other boxes colors to balance the weight. Ie. Use same middle border but one of the other colors.

I'd remove the navy blue dots and do a border in a small print on a black background.

Narrow white, red, then black binding?

I love your quilt, it's adorable. I think you need a border, however, not the pindot fabric. I would use a narrow red border or red flange, and then a solid black or a black fabric with some variation but the fabric reads as a solid. I know what I mean, but I'm not sure how to describe it. I guess it would be a type of blender black fabric, that reads as a solid black. Hope this helps.

I, too, love your quilt! I am good with the dots but would want them on all 4 sides, then I'd add a red border and bind with the same red or with a black. The larger dot would also work well instead.
I am in the minority in not minding the lightness of the upper block. I think they all work together in the overall design and that the border will bring it all together.

love the cats. it does need a border. Some thing in a solid on the sides that goes with the blocks. I'd do solid black. Then at least 2 more borders. One should be red. One could be the black and white dots.
