Oh, that looks great, Bev. I would add a narrow black border, maybe 2 or 2.5" wide. I'd use a solid or a fabric that reads as a solid. I really like the way you assembled the blocks. Good job.

Oh, how pretty! Love the bold colors.

I would add a narrow black then a bright and maybe a second black border, but I tend to get carried away with borders. LOL

Turned out great! Love it!

Small black inner border, small solid border in any color, black binding.

Paula Golden spoke at our Guild meeting last night. The topic was Judging Quilts, all of which is relevant to the heart & soul we pour into making our quilts. I know you aren't entering your quilt in a competition, but the topic included borders, and she said to always evaluate the size of the border, making sure the border is big enough to carry the (visual) weight of the center. Her trunk show included only her quilts and she spoke about what she should have done differently (judged) - not for competition, but to please herself. Larger borders is what stuck to me.
All that said, I would either make a small black border, suggested by Lois, to allow a place for the binding so it would look bordeless-OR- I would
would put a BIG Black Border on this quilt to allow those awesome blocks to float and shine.
Depends on the finished size you want the quilt to be.

Looks great!
I'm not a border person; however in this case the blocks are bold, so I' m incline to say go for a larger black border and binding which will frame your wall hanging...no matter what you do it will look great!
