I don't think it needs a thing! It's gorgeous.

I love your quilt!

Is it difficult to work with a black fabric?

I do have some problems with black fabric. I have difficulty seeing if the edges are aligned with each other when sewing two black pieces together. Sometimes have a hard time determining the edge of the fabric from the edge of the pressure foot. Multiple floaters in my eyes don't help.

I like it as is. Not all quilts require a border.

It is beautiful. Depends on what size you're happy with. I love it.

Love your colorful graphic quilt

Your quilt is beautiful. Did you have a pattern or is it your own design?

Very pretty!

Beautiful quilt and I agree with everyone here-don't think a border is needed. A border may distract from your pretty quilt

It is lovely as it is.
